Tezzeret's Rise
Sooner or later Nicol Bolas will fall. Upon his defeat, Tezzeret, who will either have been gravely wounded during the fights or have his body reanimated by Bolas failing him, will replace all of his body by etherium, becoming an aether lich.
His soul will be damaged by that, and so will his Spark, but as an inorganic being he'll still be able to travel between planes thanks to the Planar Bridge. In this state, he'll take back some of Bolas's ressources and schemes as his own and become a new major villain of Magic, possibly commanding the remaining eternals too (laced with etherium?)
