Corryn Casnar, vagabond mercenary and unsung hero of his time. Were it not for his tenacity in his efforts to remove the threat of an immortal thief from usurping the throne of his people, the cirran may very well have been enslaved and controlled by such a tyrant. Unfortunately, during a climactic battle with the thief (an amulet-bearing garion* youth named Thraddon), the land opened beneath him and was swallowed alive, presumed dead. Prior to this battle he alerted the throne of Thraddon's plans, resulting in an immediate defense that caught Thraddon by surprise and resulted in his very own enslavement far beneath the surface of the very citadel he wished to corrupt and usurp.

As for Corryn, none have seen him since. A few centuries pass before an advanced vessel of technology emerges for the sake of prophetical fulfillment. This "thing" calls itself "Longcoat," carrying with it a rather familiar weapon...

Or, uh, something like that, anyway.

*Edit - Gah, just noticed I didn't explain what a "garion" is. The garion are pretty much humans in every way. They originally ruled the continent of Kantire, but when they grew too power-hungry and oppressive, the cirran (Corryn's race), mammon (Komari's race), and the stratus (sky-dwelling humanoids resembling biblical angels) drove them out before anything could be done about it. The cirran were given control of Kantire under a sort of "Lordship," which is like similar to a monarchy. The garion still exist, but they are scattered, mutated, or at the very least living out ordinary lives with no hard feelings.
