Umbral Crusade

The Umbral Crusade was a secret war that took place in the Greenwater Nebula. It was fought by the Altusian Brotherhood against the Dark Warriors that inhabited the area.

Overview
With the rise of Infra as a powerful, charismatic figure, the Altusian sect of New Age Omni had gained significant favor over more traditional beliefs about the Harbingers and Vernietigen. Because of this, the Altusian Brotherhood enlisted assassins who would drive the Dark Warriors from the territory of the Confederacy of Greenwater so that their religion would face no opposition.
