Liang Siwang

A royal from the Qing dynasty that was revived by Thanatos just for fun. He doesn't have any wishes or desires in the world except his need to devour its energy. He dislikes people that try to touch him or come near him, and treats others as if they are under him. Siwang is very deceptive though, and despite his degenerated state of mind, he's able to act friendly and coerce others to get what he wants. Siwang wants to spend his time in dark areas away from people.

“Granny looked up at the zombie. He was - or, technically, had been - a tall, handsome man. He still was, only now he looked like someone who had walked through a room full of cobwebs.

'What's your name, dead man?' she said.” 
― Terry Pratchett, Witches Abroad
