Really enjoyed this, and have a strong idea on how to play it! Tightening up exactly what's happening with "the pilgrim's transcendence" is about all I had question-wise on how to run it.
Super small thing, but I love how the gradient bars are always alternating between dark and light, so it never bothers you how long they are or the speed they go from black to white - genius!
One design/layout point - not quite sure how the text above the title on the front page fits in, and it's likely that's the very first thing people read, italicizing (or something, not sure what?) it, making it smaller or turning it into an in-universe quote could de-emphasize it a bit.
