Necronomicon: Gravewalker (Patreon)

Gravewalkers are at home is places suffused with  death: the Shadowfell, the Domains of Dread, the  Ethereal Plane, ruins of long death civilizations,  and wherever spirits of the dead gather. Most  rangers choose this archetype after being brought  back from death, being haunted by a spirit, or those that want to help or use the spirits of the  dead for their own dark ends.

I highly recommend using this subclass with the  Reborn race for best roleplay potential.
