Sprung from the Rituals used by the Angels loyal to the Lord, each Bastion was created via several complex Lore evocations that were woven together in a Ritual of unknown magnificence that enhanced mortal craft and were powered by donations of Faith that is nearly unrepeatable by the returned Fallen. Modern Demons can create smaller Bastions with the Lore of the Forge, but these pale in comparison to the ancient citadels.
However, remnants and ruins of the old Bastions can still be found in the world, if one knows where to seek.
