Necromancer

They can sometimes be seen along the space ways and at port: sleek ships, black and angular as obsidian blades. These are the vessels of the dead: the Necromancers.

Necromancers appear as tall, cadaverous, near human bioforms dressed in black nanosuits. Though they don’t live in the usual sense, they do use energy; nanites infuse their tissues, reanimating them. Their bodies will break down over time, but after centuries — or millennia. Even then, the Necromancer lives on, their mind preserved in a palm-sized scarabaeus that can attach itself to the nervous system of a new host.
