Bel'thazorn's Infiltration and Betrayal

Bel'thazorn, seeing the chaos erupting during the Sister' War, took advantage of the situation to tip the scales of multiversal power in his favor. He waited for the right opportunity to strike, forging an artifact of his own creation to weaken the two sisters and consume them for his own gain. However, the artifact only wounded them, and through a final effort, the twins were able to withstand his assault.
