All supernatural creatures have connections to places or other people, called "tethers." They are an invisible, physical connection to a place or group that is limited to a certain, small distance.
- Ghosts: To their corpse.
- Vampire Queens: To the Hive, barring the need to swarm.
- Rove Vampires: To their homes, barring the need to swarm.
- Werewolves: To the pack, excepting Loners.
- Metanaturals: To the supernatural creature they have touched and stolen power from.
Forcibly being removed to a distance the tether cannot reach forces it to "snap", which can have devastating effects.
For a rove vampire, snapping the tether leads to immense mental and physical pain, and if not restored quickly, possible death. Even if restored, once the tether has snapped, it can leave the vampire with mental scars that cause memory loss, delusions, frequent confusion and suggestibility.
After a certain amount of distance from the creature a metanatural has taken power from has been surpassed, it "snaps", and returns the metanatural to a human state, similar to when a Preternatural touches them.
