Homebrew Ghost Species Details

Ghosts are a race of incorporeal undead with a pact that has allowed them to stay on the material plane. Maybe it is some unresolved business with a rival or maybe it is revenge on your murder. Whatever you choose, it is important to think about how this affects your character's backstory and actions. Maybe now, your character does not want to move on and is actively avoiding fulfilling their ghostly vendetta. The problem with ghosts is if they do not move towards their goal, then they start to naturally move to the afterlife or fade out of existence. Once a ghost's grudge is completed, they do move on to whatever afterlife is in store for them.
