The Jezequiel Compound is owned by the Jezequiel family - distant relatives of the Jekylls - and is passed down generationally to next of kin. It is guarded by the family, who are Black Dogs in the same way the Jekylls are Hydes. The house's family crypt contains a gateway to a demonic realm ruled by the "old god" Lord Trash. In the episode Black Dog, Robert Jekyll's battle with Brant Jezequiel causes a crack in the gateway, through which an incubus escapes.
