Bone-hand torch

1asset bone_sconce "Bone-hand torch" complexity=3
2// the crypt's wall torch: a skeleton arm reaches out of a cracked stone patch in the wall through a
3// rusty iron cuff and holds up a pitch torch in its bony fist. The flame flickers;
4// one seed in four burns a ghostly green. Its back is flat at z = 0 so it hangs on a wall with lift.
