Nissa and Chandra arrive with unresolved affection, old resentment and opposing instincts about the coming strike. Chandra wants every trace of Phyrexia burned for Jaya's death. Nissa asks what that means for Ajani, Karn and the Mirrans still fighting for their home. The argument establishes the choice the Sylex will eventually force: whether victory can distinguish the infected from the enemy.
During the assault, Dominaria's nature spirits initially reject Nissa because the plane remembers Planeswalker betrayals. Gaea finally answers by sharing both strength and rage. Wrenn stops Nissa from mistaking that rage for her own song, yet Nissa still kills a Phyrexian whose oil could restart the infection. Mercy and containment no longer align cleanly.
The Temporal Anchor implodes after Teferi transmits the activation method. His body remains in the capsule, stretched across distant time, while the Mirran offensive begins without him. Jodah and Wrenn stay to bring him back. The assembled strike team carries Saheeli's Sylex to New Phyrexia, united enough to leave but not united on what they will do when the weapon demands a person. Teferi was not killed by the Anchor's failure: his awareness surfaced on a distant beach in the isolated nation of Zhalfir. Those left with his body did not know where he had gone and still needed to rescue him.
