Orm

Mentioned in Pyramids, Orm is a god with only two worshippers left: Arthur Ludorum and his mother.

Referred to as "Great Orm", he is normally to be found in one of the Nether Hells.

The correct worshipping of Orm seems to consist of sacrificing a goat within a double circle with occult runes, a sprig of herbs and a rope of skulls. It is said that, as a punishment for not worshipping him, Orm comes in the night, winds out your entrails on a stick and sucks out your eyeballs

Orm resembles the god Om, appearing in Small Gods, whose only two true believers are Brutha and Brutha's grandmother.
