EDIT: According to the few sources I looked in, ghosts are just people who are so attached to the real world, they just don't move on. They could be attached to the world through various ways. Some includeA: A loved oneB: A job left unfinishedC: Complete fear of the after lifeIt seems one doesn't just make a ghost like one would make a zombie or golem. Welp, it's time to bend previous myths slightly.

That's only one side of the lore. Another side discribes that, on death, a person's body, mind and soul sepperate, and talk about ways to bind the latter two together again, creating a ghost. (Also for motive, what about revenge? Something like "you hunted me, so you shall not leave this world peacefully, but instead be doomed to be hunted in kind")
