This is some great “hard sci fi” underwater shit with lots of attention paid to realistic risks. The art direction is slick as hell with an icon heavy setup that would really pop in print! I like that there’s some implication of eldritch stuff going on but it’s more or less a mundane, if alien, mutation that could be leveraged by players.
For the content itself, the amount of work that needs doing starts off seeming a bit overwhelming, but the “objectives” section breaks it down clearly enough that it feels like a part of the module’s horror more than anything else. You have a million fires to put out and not enough time - what will you do? I also really appreciate the timeline clearly delineating what Wardens and PCs are each supposed to know, that kind of information can often be hard to parse in a lot of modules and it helps me get to grips with the content super fast.
My only critique is that the treatment of "body text in white, important stuff in bold+dark navy" is kind of the only lever for visual depth/hierarchy used and it can get hard to read with how much they contrast. Reserving the dark navy for headers/paragraph starters and a lighter tone for important stuff would give my eyes an easier task!
Phenomenal stuff here. Great work!
