Osiris, along with Isis, is Dee's master, and also one of the leading Dark Elders. When Dr. Dee failed them, Isis and Osiris declared Dee Utlaga, and offered a huge reward for him. At the end of The Warlock we find the astonishing revelation that Osiris appears to be the father of Josh and Sophie! However, in The Enchantress, this proven to be false. In truth, Osiris is an Earthlord in the disguise of Elders who plots to return to a time where Earthlords rule. Osiris is also not the siblings' father. He merely found Sophie and Josh in separate places and separate time periods and raised them in the alias of Richard Newman. In Egyptian mythology he was a god of the Egyptian underworld. Later revealed he is an earthlord in the Enchantress.
