Hunters often tell stories of a rare and elusive white stag who evades capture by all those hunt it. It is said that this beast only appears when a hunter worthy enough to hunt it appears or when an experienced hunter commits a taboo, after which it is seen as a chance for the hunter to redeem themselves by successful tracking and hunting the stag.
