One way of getting here, The Concave, is through conflagration of your Soul. Not a nice way to arrive, but at least you'll have the benefit of a guide, unlike most others.
People argue about the true form of the beasts known as "Bloodtouches", since they seem to take dozens of forms. Unfortunately, their bite's effect isn't in doubt. Anyone bitten by the bright crimson beasts rapidly loses all hair; their skin color shifts to bloody red. Many people fear those under this curse; villages of blood-skinned outcasts huddle in the wilds.
