Hijos de la Noche, A Sabbat Pack based in Cuidad Juarez, fell under the sway of infernal spirits in the 1970s. Inquisitors, who moved secretly into the city following leads from other cells of infernalists they had destroyed, found evidence of this corruption. The Demon Lord known only as Imperator Somni had minions not only among the Sabbat, but also among mortal sorcerers. The Inquisition called upon the Bishops of Tijuana and La Majestad for assistance, and for a brief time, Northern Mexico was united.
The Hijos de la Noche and their mortal sorcerer allies were destroyed, and the city was taken by the Inquisition -- and is held to this day by them. But Imperator Somni seeks to reclaim the city.
