A spirit born of the elements of Ariro (chaos), Haerinero (darkness) and Naleiro (fauna), which gives it dangerous and corrupting poison powers. It eventually chose the name "Duskchaser Nightshade" for itself because it thought it sounded cool and fitting for what it was.

It eventually came to work for the Starshade Syndicate, quickly rising through the ranks and eventually attaining the position of Nightshade, which was second only to the Dark Prophet himself. Working mostly as an executioner, Duskchaser's main purpose was sowing terror and fear amongst those who opposed the syndicate.

Duskchaser was eventually defeated by heroes in an epic battle in the Syndicate's submarine base. Its frame destroyed, it returned to the spiritual plane, where it now waits until it can either gather enough Iserial Energy to construct a new frame for itself, or until a summoner performs that task for it.
