Re-trapping Ulamog

We have to— Jace began, but Nissa was already gone, leaping toward the out-of-place hedron. She released his mind as she sprang off the rock— she released his mind, not the other way around. She didn't exactly kick him out, but he didn't think he could have stayed if he had wanted to. That was a powerful thing. This elf was powerful.

Then suddenly a blue flash lit up the inside of his eyelids, and the pressure on his shoulder vanished.

Gideon stumbled forward with the momentum stored up from the force he had been exerting on the titan. He caught himself just before he tumbled off the front of the floating rock... which meant there was nothing else in front of him to stop his fall. He was no longer standing face-to-face with the titan.

Ulamog had been pulled within the bounds of the hedron prison— and the prison was glowing, glowing a brilliant blue. The gleam flooded Sea Gate, drowning out the shadow of the great Eldrazi.

"Ha!" Gideon thrust his sural in the air. They had done it. Ulamog was trapped.
