Hidden among the tree's pathways was the place Teferi had spent centuries trying to recover. Zhalfir had survived its isolation, built new generations and prepared itself in case the war outside ever reached it. Wrenn opened contact and asked Teferi for help.
Her solution was larger than bringing one planeswalker through. Wrenn and Eight forced a change in the Multiverse's arrangement: Zhalfir moved into New Phyrexia's position while the Phyrexian plane was pushed out into the darkness between accessible worlds. The exchange gave Zhalfir a way home and denied Norn the network on which her invasion depended.
Teferi did not come alone. Zhalfir's armies crossed the opening and joined the Mirrans, bringing discipline, time magic and numbers to a battlefield that had nearly run out of defenders. Teferi's oldest failure became the source of the resistance's final strength.
