Ihviryn

Ihviryn was an Antecedent and Starghast who returned to Eia during the 18th Century ASR, in the material form of Devyntias Amberfern. He was initially tasked to help prevent a world war that had been foreseen, but during the transitional process from the Follow to the Material, he was pulled back due to a miscalculation in time. This initial 'unplug' caused an incomplete corrupted version of Ihviryn to manifest on Eia, who developed his own consciousness and became Thraez. Ihviryn was sent once again to the Material and was born as the aforementioned Prince.

Ihviryn's dual existence caused a never-before-seen disruption in the Material. Thraez and Devyntias were mortally linked, and shared echoes of each other's pain. Upon discovering this, Devyntias attempted to kill himself to rid the world of his mirror image, but Thraez was able to prevent him from doing so through the use of innamactic powers. This caused a life-long struggle for both of them, working against each other but reliant on the other to protect them from harm they themselves could not prevent. Eventually, Devyntias convinced Thraez that their presence on Eia was the result of a mistake, and the world would be better off without them. A last battle killed them both, and Ihviryn was returned to the Follow a complete entity.
