Duskwalker
Source Pathfinder Advanced Player's Guide
Thanks to an ancient bargain, your soul has been reborn as a duskwalker, a planar scion with a connection to psychopomps and the Boneyard. You gain the duskwalker trait in addition to the traits from your ancestry. You also gain Low-Light Vision, or you gain Darkvision if your ancestry already has low-light vision. Neither your body nor your spirit can ever become undead. You can choose from duskwalker feats and feats from your ancestry whenever you gain an ancestry feat.
