Fireworks (XII)

The chamber started collapsing the moment Valcroy's [All for One] connected with Dagan. Just the force behind the attack not only obliterated Dagan's head, making it difficult for even an expert to piece it together if given days, but also sent vibrations racing through the already fragile structure.

The cracks spidering across the walls increased, and the ceiling started giving way. Chunks of stone broke free from their prison and plummeted to the ground, ready to crush anything in their way. 

The groaning of the stone intensified, echoing through the chamber as if the very mountain above them was screaming in protest. Massive stalactites fell, shattering on impact and spraying debris in every direction, puncturing the already torn corpses on the ground. The ground beneath their feet shifted, tilting as the structural integrity of the chamber finally gave up on life.
