With the allied base fully deployed beneath the dome, wing after wing of World-Destroying Wings burst out and spread their wings in flight, dragonflame pouring down and beginning to scorch the Abyssal Legion on the ground.
Once the Evil Spirit Tribe, Black Knights, and Snakefolk armies were swiftly wiped out, the forces charging from the giant passages of the Dark Fortress consisted mostly of Dark Ones, Nether-Scaled Tribesmen, and Twisted Treants.
