Yes. I did jam pack this module. I was just so inspired. There's a virtue in being concise and cutting the fat. As the writer I believe all of it is necessary to be there, but that's not always true!
Regarding the Sol-mates, though, I would be hard pressed to remove that as it underlines a big motif in the game about codependency being an unhealthy relationship. The pilgrims physically and emotionally yearn for their sol-mates while the sol-mates feed of off their literal life essence. That's why you are "assigned" a sol-mate and mechanically get the "bonded" condition where you have do a sanity save to resist them calling out for help during the Long Night.
The enlightened is what this religion calls their priests and is the false promise for the pilgrims' transcendence that ultimately brings them to their demise. So both terms are needed in this case.
But I do take it seriously that the module can be dense and hard to quickly pick up, read, and play. I will look into ways to cut some fat after the Jam!
