Alastor is the Lord of the Crimson Realm to whom Shana is bound. He is known as the "Flame of the Heavens". He expresses his will through a divine vessel called the Cocytus, which (in Shana's case) takes the form of a pendant. Alastor is considered to be one of the strongest of all Lords or Denizens; in fact being one of the true Gods of the Crimson Realm.
