Demon worshippers

The Demon Worshippers were a sect of humans that were planned to appear in Soul Reaver 2 - presumably as an enemy faction in a similar manner to the Vampire worshippers of Legacy of Kain: Soul Reaver. Ultimately, no such class was featured in the finished title.

Background
Previews of Soul Reaver 2 in the August 2000 issue of Electronic Gaming Monthly listed a host of featured that were planned for inclusion in the new title. Among these was a discussion of enemy types and NPC's, attributed to animator James Guilford:

The retail version of Soul Reaver 2 allowed many of these classes to be identified and named, however several of the classes were notably absent from the final game and appeared to have been cut during the process of development - among them the demon worshipping class.

Little is known about the specifics of the class. Presumably they would have featured in the demon-infested Post-Blood Omen era and would, as their name implies, have developed a symbiotic relationship with the demons of the era, venerating them as deities. No other details have been made public and no footage or artwork is known to exst; presumably meaning that the idea was scrapped at the concept phase and not implemented in any fashion.
