The Eternal

The eternal is an entity that resides in the shadows of the multiverse unseen by the prying eyes of others. Your patron could be any being of necromantic origin. You may seek to serve your new master, to escape their watch, or to even destroy them but one thing always remains the same, you shouldn’t be alive.

Unlike other warlock subclasses The Eternal’s spell casting modifier is Constitution rather than the usual Charisma.

When making an Eternal warlock one thing always remains the same, you are not truly alive, you are a corpse raised from the dead to serve the will of your master.
