Grell has been known to have been having a relationship with Guildmistress Gylwyn, of the Moon Mages. Grell has never been a member of the Moon Mage Guild (he was denied entry by the entire Council) even though he uses lunar magic. Guildmistress Gylwyn was under Council investigation under the suspicion that she betrayed the Guild by teaching him its secrets. The nature of his involvement in the events of the Mirror Wraith Prophecy are not fully understood. He had been pursuing Penelope for a while, for unknown reasons. When she died, though, he proclaimed in concert with Demosel that she may have been our only hope. Grell was implicated by Andraethu in the attempted assassination of Taramaine. Andraethu claimed that Grell hired him to perform the deed.
