Editing Geist: The Sin-Eaters (section)

=== Barghests ===
Animals, for the most part, do not leave ghosts. It is very rare for an animal to leave any kind of ghost.

When they do, Barghests happen. A Barghest is a catch-all term for any non-human ghost, initially used for the trend of spectral dogs seen in the 16th and 17th centuries, but has since expanded wildly into being any creature that happens to have left a Ghost behind. Most of them live short afterlives, being pulled inevitably into the Underworld and then into the Rivers. Those who can get called away by animal-controlling ghosts get a pet to hang out with. Some of them are your pet dog or cat...but then there are some who are still living the old life, such as Tigers prowling the streets, or feral animals locked in eternal bouts of rabies.
