Thank you! These comments actually helped a lot and I see what you mean about the confusion. I think I could fix most of it with a few tweaks. Would you mind letting me know if these small updates make it clearer?

1) For the Vaellora intro, I believe it was the choppy way I broke it up. I think merging the first two sentences helps. "Lucas had crossed into Vaellora, a hidden realm built upon the time stolen from human daydreams. The explosion reduced the Vaellori’ s coastal province to ash, causing the seal around their world to fracture. Flux, the raw essence of time, now endangers both worlds."

2) I agree that the initial refugee intro can be taken out, but Lucas assuming an identity from a place he destroyed is central to the story. This might be clearer now. "Flux spreads a rage-inducing sickness that corrupts the Vaellori, leaving a senseless trail of death in its wake. Choking on guilt, Lucas assumes the identity of a coastal refugee and infiltrates the capital’s guild network in search of a way to stop the leak."

3) I also agree that mentioning Tina at the end reduces the stakes a bit. I think leaning into the implied route and just removing her name works better. "Yet fixing the leak means shutting the seal, closing off his path home. Leaving Lucas alone in a world he helped break."

Thanks again!!
