Ghost

From MeiLinWiki

Ghosts are a kind of magical creature in the world of Scryer's Gulch. Other known magical creatures are demons and Were-Folk.

Ghosts are the spirits of people who died violently or otherwise under difficult circumstances, e.g. in mining accidents, bar fights or hangings. Most spirits are too weak to manifest and all are bound to their one spot except on Halloween. On this one night of the year, ghosts are free to roam. When the sun comes up on All Saints Day, all ghosts are whisked to their usual haunts.

While ghosts may or may not be friendly towards humans, they are usually friendly enough to each other.
