The art was pretty, there's some information on Iniquity, a couple of small story hooks, and a reasonable selection of NPCs and NPC ships.
However, it felt quite railroady, and I didn't see a lot of resources or interesting ideas useable outside this adventure. All in all, it's just another pretty formulaic dungeon crawl.
To expand a bit on the railroadyness, I particularly disliked the conductor NPC. "Oh, yeah, all the secrets you want to know about are in this one place, let me take you there." I would rather give the party bits of information until they decided that they wanted to go to this place - or not. Grabbing them by the hand and telling them they should go to this place is not something I would want to do. They do give an alternative path if you kill the conductor, but it's just to replace him with another conductor. There is not so much as a sidebar giving tips for alternate ways to get the party to want to get on the railroad tracks. Sure, I can come up with my own ideas, but given the unimpressive nature of the adventure, at that point I may as well just create a wholly original one.
This adventure wasn't much to my liking, but it's not without some redeeming value, hence my rating.
