We were finally able to understand and accept the mad passages of the Grimoire of Transfiguration and thus we have learned the horrible origin of demons and dark ones. It seems the Cult of Apocalypse is taking its victims to Hell (quite literally) and there it uses the 'Anvil of Souls' to turn them into demons. The Mystery Patron alludes that she might want us to go to Hell ourselves to stop the Cult.
