Considering the Hydra's powers, Zach was expecting to step into a fiery wasteland akin to the one the First Child created on the thirtieth floor. The Hydra had waited until it woke up and not done anything but fight Yanael lightheartedly in the Labyrinth, but once it was free, there should be no reason for it to hold back.
However, instead of fire and ash they expected, Zach, Yanael, and Mandra were instead greeted by a sight of ice and smoke. Before they could do anything, a bang rang out, and stone went flying in all directions.
Zach's barrier blocked the pebbles and stones that reached all the way to them.
They turned toward the source of the commotion and glimpsed the action through the smoke and shards and blocks of ice covering the buildings, or what remained of them.
The Hydra was on the ground, bleeding. A boulder of ice was pinching one of its wings to the ground. Its other wing was in tatters with large holes in it like a ripped sail.
