Pan Sagittarius (2509 CE)

Pan Sagittarius conducts a mission to the legendary if-nodes of Antan - the center of time and space where unrealized histories are stored. His assignment: to enter the mind of a key person in a historically crucial moment to affect his host's motivation (without forcing his choices) to make possible an alternative outcome. And Pan does not enjoy immunity from the consequences. His existence, too, is at stake!
 
Pan is one of the great heroes of science fiction- a lusty, resourceful adventurer whose wit and seeming recklessness conceal a profoundly brilliant intellect.
