Why are these kinds of Revenants worth so much? They will hardly be out for adopts for this species as they are extremely rare hence why they are called Unheard of's. If you see a Unheard of Revenant the prices going for them are sky high, if you manage to get a breeding pair of Unheard of Revenants, the babies will go for just as much if not more.
Unheard of-Unheard of Revenents are far beyond any rarity, they are pretty much like celestial beigns or a myth in legends. Unheard of Revenents ONLY HAVE ALBINO COLORATION with hints of stars in their fur or on their bodies.
