In the world ability circle, Black Sorcerers form a faction, akin to the sinister and poisonous black magicians seen in Western thrillers.

Be it abroad or at home, both are quite wary of people cursed like this, so their corpses are buried on this island, no one knows exactly where, maybe it's the beach or the square we walked past..."
