In Beast: The Primordial, Beasts and Heroes have a Life and Legend instead of a Virtue and Vice. The Legend describes some key aspect of the Beast's Horror or the Hero's self-image as a mythic monster-slayer. Some suggested Legends for Beasts are "restless," "unexpected," "vicious" or "watchful." 
A Beast who acts in accordance with their Legend regains Willpower, much like a Vice.
"Legend" is also used in Beast as shorthand for an individual Beast's life and reputation, and by extension the metaphysical framework that contextualizes their existence. Beasts who purse the Incarnate Inheritance attempt to transcend their Legend and become truly mythic.
