The Stone Of Attamon is a powerful fragment of the Comet Of Lost Souls (Attamon). It is a red ruby-like stone which fits into the Hellbound Amulet (Scottish priests, formerly. Rookery, last known owner!) or the Amulet Of Lost Souls (Sackville-Baggs). Hellbound allows Vampire Hunters to send vampires to Hell. Lost Souls allows vampires to become human. Every 300 years, the opportunity to use the stone comes.
