The movements of one "Alias Strang" during the Ilythian incident are vague and incoherent. He made contact with the Ecclesiarchy and was presumed dead after the gun battle at the storm-lashed Reliquary of St. Jesov. Apparently he escaped with not insignificant injury and was last sighted aboard the Valkyrie which exploded in the debated Saint's last moments.
Some say manipulation of the supposed Saint was his aim, and the Valkyrie voyage a desperate attempt to have some bearing on her destiny. As neither have been since, one must presume that his mission failed.
However, Strang's lack of known identity will make it impossible to state definitively that he is indeed deceased.
