Dude hell yeah. This goes so hard. Love the drama of the setup on the first page and the counterbalance of Ugzor the Hater just being a chill asshole, minding his own business. Perfect balance between high stakes and committing to having a bit of fun with it.
The gull cartel I think are really key to this working - grounding the whole adventure in the bad actions of a more grounded idea (tomb robbers unearth something they shouldn't) and provides tangible group of antagonists for the first half of the adventure. It's really sticky, gives something for the party to get to grips with before things escalate to the astral realm and the star crystal prison and the mega spliff.
Visually great too - I can smell the paper.
