This rules. Really clean, great map and mechanical instructions, really creative. A few minor layout issues, especially on the spread, but nothing that meaningfully detracts from the work. Only things I'd really like more of is some sort of mystery for the crew to chase: I don't know if the adventure has a clear path for the crew to discover what's going on or why, but it's not really necessary and even if you wanted that it's not a super heavy lift for the DM.
