Chaos pantheon — the cosmic cancer
This god possesses a power which changes all that is good into that which is bad. Pocharngo corrupts from without — nothing which it touches is safe from degeneration. Like a growing, slogging swamp, it even turned the old world into a sickening tumultuous slough of cancer. Portions of things which Pocharngo touched ran before it and outside it, and some of these cancerous parts even now run free. In ancient times it was stopped only by Zorak Zoran, courageous fighter for the world, who shattered its whole body and turned it upon itself, changing the evil into impotency.
In Zorak Zoran rituals, the sacrifice who takes the part of Pocharngo is stripped and painted with a special, foul-tasting slime.
