Bloodlines of Darkness: A Trinity of Sorcerous Origins

From publisher blurb:

Have you ever enjoyed playing a darker character, perhaps someone that cares little for the greater good, or simply someone with a moral flexibility?

This is but a mere glimpse of greater horrors to come, this product features a number of new character options, or just a few new options for antagonists. Much of these will be included in a future supplement, however, we wished to pull back the curtain and reveal"

Three new Sorcerer Bloodlines:

Mistwalkers: the bloodline from the Ethereal Realm
Infernal: scion of devils and demons
Deathborn: the children of vampires

Several new vile magic spells, including Festering Grasp and Unholy Transformation.

Three new magic items including the Writhing Blade.
