Gods of rebirth, life and death. Two headed serpent, they are two sides of the same coin, the endless serpent, Alchemysteth is about balance; for a life to be given, life needs to be taken. What comes from Earth returns to Earth.

Al'chemysteth took mortals into his garden, gave them a soul, a mind. Taught them alchemy, the ancient science of immortality.
Worshippers were blessed with alchemical abilities with sacred knowledge to create the Philosophy Stone.

Also considered the god of wisdom. They gave mortals the knowledge of alchemy so that they would also be immortal.

Celesteh declared war on them for giving forbidden knowledge to mortals. After the great war, Black Alchemysteth ate White Alchemysteth, devouring themselves entirely, but just before they finished, Celesteh sliced their head off.

With them died the ancient knowledge of Alchemy. Southern priests who remember the old days still wait for the day for Alchemysteth to be reborn.
