Shadowhunter’s Codex

by Cassandra Clare

  This heavenly fire is very potent against demons. Most demons can heal themselves from mundane injuries in our world fairly quickly, just as werewolves and vampires can. We Mark our mundane weapons (see sections below) to make them more potent, but even so, the best we can do with them is damage demons enough that they must retreat to lick their wounds, as it were. Only the seraph blade can permanently damage a demon, so that it must withdraw for more significant and lengthy healing or must return to the Void to repair itself.

  After a time the power of an activated seraph blade will be exhausted, and it will need to be refreshed by the Iron Sisters in order to be used again. Depleted seraph blades can be brought to the weapons room of your local Institute for regular recycling.

  Iron Sisters also badass at recycling!

  Note that the seraph blade is a viable but drastically overpowered weapon in a fight against a mundane. Downworlders are harmed by them in much the same manner as demons, but mundane flesh pierced by a seraph blade will burst into flame and may consume the mundane entirely. The Clave has officially deemed this “awesome.”

  Shadowhunters will not be so burned by seraph blades, given our angelic blood, but even so, activated blades can severely burn the wielder’s hands, and you should not touch a seraph blade until you have been Marked with the rune of Angelic Power. (Typically this is placed either at the base of the throat or on the inside of each wrist.) A Shadowhunter who has been stabbed by a seraph blade will not burst into flames, but it should be remembered that seraph blades are still blades and can kill a Shadowhunter by more terrestrial means, like any other sword or dagger.

  By the way, most Shadowhunters think we have to name seraph blades just because Jonathan Shadowhunter thought it was important to make everyone memorize a lot of angel names. That guy was hard-core.

  It does mean you rule at Angel Trivial Pursuit.

  Also Angel Scrabble.

  MATERIALS

  You’ll find weapons made of all kinds of materials in your local Institute, chosen for their magical properties.

  ADAMAS

  Adamas is the heavenly metal granted to the Shadowhunters for our use by the Angel Raziel. The metal is silver-white and translucent, and glows slightly (although this glow may not be visible in broad daylight). It generally feels smooth to the touch, like glass but notably warmer and heavier. It is the hardest substance the Nephilim know of, and cannot be worked by mundane means. The Iron Sisters use seraphic Marks unknown to non-Sisters to shape the metal; to craft weapons and steles from it, the Sisters use forges that take their fire from the heart of a volcano.

  IRON

  This element is toxic to faeries. You will often encounter the term “cold iron” in reference to the fey; this is just regular iron. The term “cold iron” refers to the fact that it is cold to the touch, which was at one time believed to be associated with its magical properties. Iron takes enchantment and blessing very well. It’s generally believed that it is the large quantity of iron in human blood that causes its affinity for enchantment. It is especially worth mentioning that meteoric iron, the nickel-iron alloy that makes up many meteors, is a particularly good conductor of magical energy.

  STEEL

  This type of iron alloy is usually not toxic to faeries. It is the purity of iron that grants its power over the fey. Steel does, however, hold a sharpened edge very well, and thus the Shadowhunter will normally spend a large amount of time training with steel weaponry to learn how to put one of those sharpened edges through a demon.

  SILVER

  Silver is a metal with which all Nephilim are intimately familiar. Using a weapon made of silver is one of the only ways to permanently injure a werewolf, who will heal from a wound made by any other material. The element is toxic to vampires and causes them to experience pain, headaches, nausea, and so on, though it will not kill them. Silver is a potent conductor of magical energies, behind only gold and adamas, and as a result the fey also use a large amount of it in both their arms and armor, and also in their decorative arts. Shadowhunters have the unenviable task of learning to wield both steel and silver weapons, which differ noticeably in weight, and the Shadowhunter must in fact learn to switch between them quickly.

  GOLD

  This metal is poisonous to demons. It is also an excellent conductor of magical energies, although it is rarely used to make weapons or tools, since in its pure form it is one of the most soft and pliant metals. Interestingly, it has both strongly positive and strongly negative associations in religious ritual. On the one hand its rarity, resistance to corrosion, and beauty has caused it to be used to symbolize high esteem, power, and the light of Heaven. On the other hand its expense and rarity has made it a symbol of greed and of the profanity of material wealth, as opposed to the sacredness of spiritual wealth. Thus, one will find gold used in sacred and powerful religious decorations and also in some of the darkest of demonic rituals.

  ELECTRUM

  Electrum is an alloy of gold and silver that can be found naturally in the earth. It has been known and used since the time of the pharaohs of ancient Egypt. Its lack of purity means that it is rarely used in specific rituals, but it is considered a good conductor of magic. It combines the mystical abilities of both silver and gold, in lesser strength than either pure metal but at significantly less expense than pure gold and without some of the disadvantages.

  COPPER

  This element is used mostly as an intensifier for other materials. It is thought to help bring the abilities of other metals into better alignment with the wielder, and thus is often used decoratively, or to form hilts or handles of silver weapons, for instance.

  DEMON-METAL

  Demon-metal is a noble metal (that is, one resistant to corrosion) that is believed to originate in the Void, and cannot be found naturally in our universe. It is black in appearance but is believed to be transparent and glowing with black demonic power. It is something like the demonic equivalent of adamas in that it creates wounds that cannot be easily healed by seraphic Marks and require much more involved medical attention. You will find it sometimes used to forge weapons or armor wielded or worn by demons themselves. It is incredibly rare to find it in the hands of Downworlders or humans.

  ROWAN

  The European rowan tree has long been known to have magically protective properties. It has been used in Europe to ward off malevolent spirits and enchantments for thousands of years. These properties, along with the tree’s density and strength, have made it a common choice for the staves of druids and other priests, and it is commonly used in the construction of Institutes and for arrows wielded by Nephilim.

  ASH

  The wood of Yggdrasil, the world-tree of Norse mythology, is believed to be the source of the so-called Mead of Poetry, the mythological beverage that would magically transform the drinker into a scholar. It has properties similar to that of rowan but is notably easier to work. It is also often used in a similar way to iron—it is believed to have a similar affinity with humans. (Norse mythology also cites it as the wood from which the first human was created.)

  OAK

  The oak tree is often considered the “most mundane” of woods, and from this very fact it draws its power. It has great strength and hardness and is therefore frequently the material of choice for wooden weapons. Stakes for vampire slaying, for instance, are traditionally crafted out of oak, which is believed to help guide the wielder’s hand to the source of demonic magic, in order to eliminate it.

  Jace is considered the most awesome material to make a Shadowhunter out of.

  I am both grossed out and confused.

  HOLY WATER Batman!

  You probably already know of holy water. In fact the use of water as a weapon against evil is well-explored in myths and legends. Water is the substance that, more than any other, defines and sustains life in our world. It can be made, with the application of ritual, to take into itself something of the angelic, to become not merely the wate
r of life but holy water. Holy water has proved to be a useful weapon against demonic powers: It is severely toxic to demons and also to vampires. It can be used to flush out the beginnings of vampire infection, to save someone who has ingested vampire blood. (See the Bestiaire Part II, Chapter 4, for more details.) Faeries, on the other hand, can stand its presence and its touch but will be made severely weakened and ill if they can be fooled into drinking it. (Interestingly, werewolves are not affected by holy water at all, just as they are not at all negatively affected by other mundane religious objects.)

  That actually is interesting! Ask Luke about.

  Many mundane religions include this notion of seraphically aligned water, and it is from the mundanes’ holy men and women that the Nephilim acquire the majority of our holy water. As part of our relationships with mundane religions, we maintain connections with monastic orders across the globe. One of these orders’ responsibilities is to bless water and other objects for the Nephilim. The orders connected to the Nephilim tend to be among the more secretive monastic orders, often those sworn to silence, and the relationships are often kept up by Silent Brothers and Iron Sisters.

  How we collect, store, and distribute all this holy water to the Institutes and to Idris is a fascinating hydrodynamic engineering problem that will not be gone into in this text. Those who are interested in more depth are encouraged to visit the Silent City, where the research Brothers there will be more than happy to supply you with the multivolume handwritten tomes they have created specifying the processes, for perusal at your leisure.

  No need to be sarcastic, Codex.

  I think that’s sincere, actually.

  Wow.

  ARMOR AND OTHER TOOLS

  Black for hunting through the night

  For death and mourning the color’s white

  Gold for a bride in her wedding gown

  And red to call enchantment down.

  White silk when our bodies burn,

  Blue banners when the lost return.

  Flame for the birth of a Nephilim,

  And to wash away our sins.

  Gray for knowledge best untold,

  Bone for those who don’t grow old.

  Saffron lights the victory march,

  Green will mend our broken hearts.

  Silver for the demon towers,

  And bronze to summon wicked powers.

  —Old Nephilim children’s rhyme

  SHADOWHUNTER GEAR

  One’s first set of Shadowhunter gear is, for most Shadowhunters, an important moment in their training—the time when they begin to first look like other Shadowhunters. When you wear gear, you become part of a tradition joining Shadowhunters across hundreds of years; our gear has remained basically unchanged since modern textile methods came into being.

  Battle gear is crafted of a well-processed black leather, created by the Iron Sisters in their Citadel, stronger than any mundane leather and capable of protecting the skin from most demon venoms while still allowing for swift and free movement. Nephilim on regular patrols or similar excursions may choose to wear only the basic gear, but those preparing for battle will often add bracers and greaves, traditionally of electrum (see “Materials” ). Both the gear and accessories such as bracers are typically Marked, both with runes of protection and strength and with more decorative symbols. These might include family crests, Marks commemorating battles, names of angels invoked as protectors, and so on.

  The standard Shadowhunter gear involves, for both men and women, simple flat-soled shoes and sturdy, closely fit trousers. For most of Nephilim history gear differed between men and women—men would wear with the above a closely fit waist-length shirt and sometimes a jacket, whereas women would wear a long belted knee-length tunic. This tunic was always a less practical choice, and was worn historically to maintain the standards of modesty and decorum that were required of women as they moved through mundane society. In the past fifty years or so, the use of this tunic has faded in favor of more unified, unisex gear worn by male and female Shadowhunters alike.

  THE PROBLEMS OF TRADITIONAL ARMOR

  Many new Shadowhunters through the years have arrived at their first day of training proudly clad in their family’s ancestral plate armor, as if they were going off to fight the Hundred Years’ War. (Obviously this problem was at its worst during the actual Hundred Years’ War.) In truth this kind of heavy armor is not very useful to Nephilim; standard fighting gear is preferred, and the specifics of the gear are less important than one’s weaponry. The mundane world went through a complicated “arms race” through the Middle Ages regarding armor. Both weapons and armor gradually improved in effectiveness, with new weapons designed to pierce armor, and then new armor designed to withstand those weapons. Armor reached its apex with a somewhat ridiculous full suit of steel intended to stop a blade or an arrow, and became rapidly irrelevant with the advent of artillery and firearms in mundane warfare.

  Shadowhunters never participated in this silly exercise. First, Shadowhunters have always, by necessity, prioritized such attributes as freedom of movement, detailed assessment of the environment, and swiftness over raw strength of material, and as a result were rarely tempted by heavier, bulkier armor. Second, the fact is that mundane armor is designed to protect the wearer from the attacks of other mundanes. We, on the other hand, frequently face foes who wield magic, and who might on any given day attack us with fire, with excoriating acid, with bolts of demonic lightning, with venoms and poisons of all kinds. We know of no material—including adamas—that can keep a Shadowhunter safe from all of the devices at the disposal of our demon foes. We therefore have always had to learn to avoid harm by our wits and reflexes, since no amount of steel covering our bodies would truly keep us safe.

  THE EVERYDAY CARRY

  Shadowhunters do not typically travel heavily loaded with equipment. What they take with them on patrols or investigations must not slow them down very much, or compromise their agility. Thus they typically prefer small tools, lightweight and easily kept in a pocket. Most Shadowhunters will find a set of tools that they will take with them everywhere; it is worth some time considering what tools you find useful to keep on hand. Some common tools are here suggested, and described in detail where necessary.

  TYPICAL SHADOWHUNTER EQUIPMENT

  —Gear

  —Primary weapon

  —Two seraph blades

  —Ranged weapon (e.g., crossbow, sling) (Optional)

  —Stele You’re kidding. Lame. Okay. Custom lesson from Jace here. Yes, take all that stuff.

  —Witchlight

  Actually, carry two witchlights. Some other stuff that I always carry with me on patrol: chalk. A multi-tool with screwdrivers and two knives and a corkscrew and all that. A sturdy watch. A strong folding utility knife. A butane lighter. A phone.

  —Sensor

  If you are also carrying a backpack, I recommend throwing in nylon rope, a small crowbar, binoculars, a basic first aid kit, a spare stele, two extra seraph blades. Oh, and rubber gloves. Every so often you’ll be very glad you have them.

  THE SENSOR

  The Sensor is a common Shadowhunter device for detecting demonic activity. Sensors have varied in design over the years, but today the Sensor is usually a small handheld oblong made of a black metal. It bears some resemblance to a modern cellular phone or other handheld mundane communication device, but where that mundane device would have control buttons and switches labeled in a mundane language, the Sensor is labeled in Marks whose meaning must be learned. The original Sensor was invented in the late 1880s by Henry Branwell and for a time revolutionized the pursuit and capture of demons. It’s a tricorder.

  What? What is a tricorder? Three . . . cords?

  Unfortunately, the Sensor is somewhat limited in what it is able to sense. It functions as a frequency detector, tuning in to the vibrations that demons create as they pass through the magical ether. These vibrations vary by demon species and change in intensity based on the
intensity of demon activity (number of demons, demonic magic in use, etc.). In theory it is possible to create a “frequency table” matching specific demon species to specific frequencies, and in fact much ink and time was spilled in the years following the invention of the Sensor, creating endless tables for “translating” specific demon signals. In the field Shadowhunters almost never have time to consult a table, and it is usually faster and easier for them to learn from experience to recognize demon types by sight. These tables are now considered mostly a historical curiosity.

  But we have wasted your time by telling you about them anyway.

  These days Sensors are designed not to be manually tuned (though most can be so tuned if the user demands it) but to scan up and down continuously for all demon activity and offer some educated guesses about the causes of any frequencies that appear. Modern Sensors may have mapping systems, proximity alarms, and other colorful features.

  The Sensor often baffles new Shadowhunters, mostly because of its control buttons, which are labeled in angelic runes. This is done to allow the device to be used universally around the world, as the Shadowhunters do not share a single common language other than the language of Raziel and the Gray Book.

  SENSORS THROUGH THE YEARSThat title makes me sleepy just looking at it.

  I have never in my life been bored enough to actually read this sidebar.

  The first Sensor used as its warning mechanism a standard mechanical metronome, which in the proximity of demons would begin to clack rhythmically, its speed increasing as the demon and Sensor grew closer together. This metronome sat atop a large wooden box clasped in copper, the copper having been elaborately inscribed with Marks, and a variety of Marked and un-Marked mechanical works inside did the sensing and ran the metronome. The whole contraption sat atop a heavy cart with four wheels that had to be pushed around, since the metronome had to be kept level with the ground at all times and could easily be disrupted by unexpected movements. Various experiments took place through the early twentieth century to try to make the Sensor self-propelled and able to follow a Shadowhunter, patrol an area independently, and so on. These experiments never resulted in any usable innovation, and more often resulted in a dangerously mobile demon-powered cart that might at any moment charge the nearest Shadowhunter with unknown intent, clacking madly because of its extreme proximity to its own sensing apparatus. This failed branch of Sensor evolution fell away from the tree entirely in the 1960s when modern rune miniaturization magic made it possible to create Sensors that could be carried in a trouser pocket.
