Constructed in the lower levels of Castle Sturmvoraus, it housed the Summoning Engine rebuilt by Vrin and Prince Aaronev VI after Loremistress Milvistle arranged for the original device to be destroyed. In addition to the Engine and various pieces of scientific apparatus, the Chapel was decorated with feminine statuary and paintings and the Geisterdamen Goddess symbol. Whether regular rituals were performed in the Chapel as well is unknown.
