Jace - Sylex detonation would destroy thousands of planes

All that remains at the end of the journey is catastrophe; Jace has his hands on the sylex, Phyrexia will succeed in their invasion, and all that is left is to desperately try to explain to his friends why annihilation is the only path to peace.

They're trying to talk him out of it, but they can only see what feels right and not what is real. They aren't listening. Jace's heart aches for the billions and billions who will survive to suffer and witness their own annihilation, and he wishes the one person whose moral compass was steadfast as stone were here to champion his argument; the Multiverse cannot persist if Phyrexia survives. We must let it start over.

Even if we win, thousands of planes die. If we lose, existence is forsaken. We owe it to the planes and generations that follow to gift them a Multiverse unpolluted by Phyrexia.

They must act. Jace knows he is a bomb. He's sixteen tons of pyrite; he's a field of upturned knives; he's a hammer surrounded by cobwebs, and at this moment, he holds his shaking hand four inches from the rim of the sylex. The cables that writhe from his arm, the appendages are his, but they recoil from the artifact. What is left of him is fascinated at the reflex; not even phyresis can exterminate the instinct of self-preservation. Which is not ideal. He needs to die promptly so Elesh Norn cannot detonate him.
