Kaiden drew Yunohana back from the changing entrance as black crystal spread across the conquered cavern's ceiling. The golden rings were still turning where the way out to the island had been, and each revolution sent another branch racing through the stone above them.
"Is it closing?" she asked.
"I don't know. Let's stay back a little longer."
She came with him, watching a crystal vein descend the wall beside the entrance. It reached the floor and divided, outlining an enormous arch where solid rock had stood a moment before.
*Crrrack!*
Kaiden felt the floor pull beneath his shoes. Across the cavern, the ridges they had fought between were spreading apart, their broken crowns sliding away from one another as fresh ground appeared in the gaps.
"Holy shit… watch out."
He caught Yunohana around the waist when the movement reached them. She held his shoulder while the stone beneath their feet stretched toward the growing arch, carrying them with it.
