The defenders did the best they could in the short amount of time they had left. But with the ship's dispersion field still active, very little damage was dealt to the ship and the inhabitants within.
As the ship hit the ground, it pulverised entire forts in an instant. Despite the five kilometre ship coming in at an angle, there was still a great deal of impact force, which as it began tearing through the crust into the tunnels below, sent a shockwave for roughly fifty kilometres, dealing massive damage and causing mass death in the first ten.
The ship finished crashing. More than half of its body had submerged into the tunnels underground. If anyone was close enough to the ship and had survived, they would have noticed the eerie silence that took hold of the surroundings.
The silence was broken, however, when the ship began to open its 'pores' and in the millions a second, Hive bio forms began to pour out of the ship like liquid filling the space wherever they needed to be.
