Hidden among the tree's pathways was the place Teferi had spent centuries trying to recover. Wrenn searched the routes Realmbreaker had never been commanded to follow and sent a branch into Zhalfir. The isolated nation had survived, raised new generations and prepared to defend itself. Teferi and his people chose to answer her call.
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 fought beside Koth and the surviving 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.
The passage created by Wrenn and Eight did more than offer Teferi a route back. Zhalfir's warriors choose to enter a war that the surviving Mirrans have fought without relief for years. Their shared battle is not a claim that the two communities have identical histories: one was displaced from the Multiverse while the other endured the conquest of its own home.
