Darvethai

This is a horrifically evil deity. To his followers, cruelty, thiefery, and murdering are rewarded.

Little is known of his creation, or origin, but we do know that his followers are evil in nature.

Mana of his own creation, called 'Dark Magic', is not specific to his followers, but they seem to use it more. It is outlawed in almost all elvish communities. This ranges from evil spells, to raising the dead.
