Dilan didn't really have a plan in mind but that was not necessary because he was strong enough to make everything work.
The Nightmares around him were wreaking havoc, while he passed through the crowded streets unharmed. Men and women were crying out in despair as they scampered around like mice trying to escape the terror that hailed down on them.
It was only a matter of time before all the Ascenders in the settlement would die at the hands of the Nightmares. After their death, Nightmares would be given birth by the deceased. This made it look as if an Undead Spirits were crawling out of the Ascenders' dead bodies.
Dilan found this to be quite fascinating because the entire battlefield around him was filled with despair, rising Nightmares, and death. The Nightmares tore the Ascenders into pieces, thrashed their skulls, and mutilated their bodies beyond measure.
