Guys guys, and it feels like I'm the only one who has read all 50 calcified fragments, Eris is listening to the Hive God Savuthan. Orxy evil sister who wanted the crown for herself. And at the end of the mission when you kill Orxy he takes himself. In the grimoir for the touch of malice it says the gun was a part of Orxy witch leaves me to believe as long as that gun remains Orxy does. The reason I believe Savuthan is because it never stated she died.
