In the Sleep of Death
The Will of the West
The Will of the West was an ancient tradition of the Great Western Powers, thought to be the Age of Erathor, when the East was still primitive. The tribute would be brought across the Vale, and gifted to the West in a symbolic fashion, in the many temples and complexes of the Will spread around the Vale.
You learned from Revan that the magic of the disparate facilities links towards the central “bowl” underneath the swamp ruins, though the bowl itself is merely a vessel that contains the energy.
You learned that the Harvest Ruins beneath Trieste were designed to incite a bloody frenzy in the people near it, and it seems to have harvested their spiritual life forces.
The heroes found several other ruins, devoted to the Erathor and the Will, but most were in only semi-functional states.
