Raised from the dead as a being of undeath, you count as an undead creature for all spells and abilities that affect the undead. Instead of sleeping, you enter an inactive state for 8 hours each day.

 Choose another living race besides this one. Before your death, you were a member of this race and appear as an undead version of it. Your size, height, and movement speed are the same as a typical member of that race. You do not retain special movement speeds from this race (such as swimming or flying), and, though you may choose to have formerly been a member of a subrace of a particular race, you derive no benefits from doing so.

 Through the necromantic energy animating you, you are able to perceive with greater clarity that which lurks in the darkness. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in dark ness, only shades of gray.

You can speak, read, and write Common and one language available to the race you chose for your Past Life.

An animated figure made of dry bones devoid of flesh and muscle, you were likely raised by a nec romantic caster or dark, supernatural curse as a simple minion, completely without will and self knowledge. Something changed, however; per haps your master was slain, the land cleansed, or you merely awoke one day to fragmented memories of your previous life. Whatever the case, possessed of a fragmented sense of self

and newfound purpose, you struck out into the wider world to find a new destiny.

Your collarbones have been inscribed with magical glyphs that help you to blend in with society.
