Kapitel 527: 8.09.4 The cloud is here.

As Dearma was enjoying the little chaos he had caused. The ground shook to a minuscule amount, which went unnoticed by many, as it can be considered the vibrations caused by a simple step. But for Dearma, a Legendary being nothing was hidden from his eyes or senses, with a simple unintrusive focus, he found something wonderful under the city. 

"Mosquitos?" He wondered for a tad bit before smiling."Is this him?" Only he knew the work he had done for the Bloodcrows. When he is forced to fight the monster known as Wortham, Dearma learns another secret about this disgusting family. 

'The chaos they warned of, is it their own blood?' 

Those mosquitos, he remembers those things, but not in this specific form. 

They were creations summoned through the blood of a particular branch of BloodCrows that Dearma had seen with his very own eyes.
