Ghost

Ghost are the souls of dead creatures, usually humans, that have not found their way into the afterlife. They have translucent greenish bodies that can be interacted with and despite already being dead, they can be killed again in combat. Ghosts are usually, but not always, found near the place of their death. Most ghosts are friendly towards the player, often offering their services as merchants, collectors, quest-givers and such, but there are also some who are aggressive and who will attack on sight.
