Dry-Corpse is a servant of the God of Unnatural Death.
He was once a man so evil that the earth would not rot his flesh and demons would not take his soul. He wanders "the unseen spaces within the earth". It is disputed whether this means the underworld, the astral plane, or simply out-of-the-way places.
He is said to be cursed with an unholy appetite for lost children (or, some say, for pregnant women and their unborn babies) "unquenchable like the craving for salt-water".
Dry-Corpse has the appearance of a great snake, scintillant and seductive.
