There are a few typos here and there. I only mention it because it doesn't fit with the historical text. Excellent work.
As for the "Rose by any other name" plot hook, maybe the follower is trying to gently convert the group, or at least bring them closer to the side of the faith. A plot hook that leads to other plot hooks. Go to Comment
I think this is your Falhathian Masterpiece! Great job! Via Mortus is something that caught my attention in previous posts so its great to see it as its own entry. History, religion, human nature, it has everything. Nice multi-layered structure. Love the Ossuary Towers and the Cathedral! Go to Comment
Really good. I especially like the moment of creation, a contract which is not much for an ice spirit, but a lot for the sorceress. One hundred years, and one day, a good duration that. Also find the insta-cult that appered and vanished again amusing.
Some parallel worlds have different time-flows, like the fabled dwelling-places of the elves: those who visit them under the hill for a night return to find that years have passed in this world. Perhaps it is the gate leading between the worlds which causes the alteration. If a gate were 'misaligned', the shift from '| |' to '| \' or '| /' as it were would lead to that difference, much as a light-beam split and bent by a prism ends up taking a longer path. There might even be a mathematical function linking degree of misalignment to alteration of time-rate.
