How was Turel's future self at Avernus Cathedral at the time of Blood Omen?
Turel's brothers were all deformed, bloated monstrous versions of themselves in Soul Reaver, but that was around 1500 years ahead of the events of Blood Omen. In Defiance, when Raziel goes to Avernus Cathedral during the same time frame that Blood Omen takes place, how is that Turel is there in his bloated, monstrous form? Was he summoned by Mortanius from the future? Did he traverse back in time like Kain and Raziel somehow? Was this ever explained anywhere and I just missed it?
