how long do wood elves live? maybe he became the next champion after being inspired to join the arena by the hero of kvatch or whatever. or died ameadiatly in the first match. OR... he could be the new Miaq (one of the more spiteful deadra prince's might have granted him imortality to torture the mortals and he gets exiled to Skryim where no one is expecting the next eddition of Elderscrolls to appear but little did they know)

if so we should tell the guards hes stalking us

He can't be in the game, he "fell" off dive rock in a tragic accident when the CoC was in Anvil on buisness.

I spawned him in the Umaril fight.
