Very polished, but there's so much packed in here that I think the readability suffers a bit.  

I do like the boss fight mechanic, but I think there need to be clearer or more straightforward links between what the Tell is, what the consequence is, and how the PCs can Cancel it. (Let us recall stories of player groups being stumped by children's puzzles)

For instance if a Warden uses "Fractured Reality" and says "The air around the black hole seems to fracture like brittle glass, you hear morbid whispering in your mind", then I think most players wouldn't understand that they can "self-reflect/confession/being true to themselves" to prevent the outcome, or that the outcome would be a copy of themselves appearing. I think they would conclude "space-time is being damaged, is about to shatter completely,  and we should evacuate".

Whereas if the Tell was "Each character sees that their own shadow is starting to take solid form. They sense all the darkest aspects of themselves slowly turning into murderous reality" Then the consequence - they have to face down their corrupted copy - is much more easily anticipated,  and the possible Cancellation - trying to repress or acknowledge the dark part of their psyche, or perhaps physically disrupt the copy from forming - is a bit more readily apparent.   

Hiya, here are some notes I took while reading this trifold! (presented in the order I thought em)

First thing is that cover art. My god it's beautiful. Made me immediately go "oh ok I need to know what the story is with this bad boy." 

The landing sequence immediately presents a recognizable threat to the PCs, which I appreciate. (not to mention the names of the anomaly & areas!)

Saw astroid (vs asteroid) a few times -- intended? (i'm not dinging anyone for typos in my ratings, anyway. just pointing em out for future versions where I can)

I think I mentioned this on the discord, but the reality check table is so good that I could see myself recycling it in other sanity-testing adventures. 

I'm not a Secret Agenda Guy so I would likely either be choosing one as the employer or having the party see them all on the job board and pick themselves. Again not a ding just a stray thought

Gorgon's Head encounter is SO COOL. the tells/cancels/results is such a great mechanic. For the combat stat, would it be rolling this on e.g. when it throws players against the ground? or is that automatic?

Taking my time getting to the inside because it is DENSE. There's so much stuff here! 

I think this is a me problem, but I am having trouble wrapping my head around the dive mechanic -- let's say we decide to start by entering medusa. I roll 3 on the d5, for entering at 1, does that mean we start at petrified forest? or are we in at antechamber but the 4 is instead the event (aftermath of encounter which i guess i am rolling now)?

As confused as I sound, that's just easy enough to confirm here and figure out. The important part is that I am imagining some of these moments in these spaces with these encounters and they seem AWESOME.

Ok, realizing I am writing an entire essay here, gotta stop soon. You made something special here, just a cornucopia of brain-twisting moments with a clear goal at the end. I'd run this! Fantastic work!

Hello Unfathomable team,
Having read through this adventure I have to say that the scope and breadth that you put into one pamphlet is impressive. It seems like this could be a 3-5 session adventure and all contained in a pamphlet is amazing. And just finishing an impressive pamphlet like this is a feat in itself so congrats on that. 

Here are the ratings and explanations that I had for each one:

Polish: 4/5

I really like the overall look of the module and it is clear that a lot of time and effort went into the layout and design because there is so much but you were able to fit everything in, and it is all for the most part very legible. I really like the cover image, it does a great job of foreshadowing the insanity of the adventure. It is a very dense adventure and I found my attention sliding off of it at times, there are also a few inconsistencies in the locations; for medusa there are little sidebars that give a little overview of the location but it doesn't seem like the other two have this style. I would have also liked some more description on some of the enemies, especially the Ephyra, I'm guessing they're some kind of bug people made by the Gorgon's Head, but it is definitely not clear. Overall very nice looking but some inconsistent writing. 

Favorability: 2/5

As this is the most subjective category this is just my personal taste. I found many parts of the adventure to be under-explained and overly complicated. I like how crazy it can get but I could not see myself running this personally. I also find depth crawls to not personally be my favorite way to play an adventure. All of the scenes, locations, and events are interesting but not as fleshed out as I would like for my table, and some of them are so conceptual that it seems hard to explain them to my players in a way that would be actionable in game. So overall this is just not my favorite kind of adventure but I find it all very creative and interesting. 

Usibility: 1/5

Unfortunately as I have previously stated this adventure seems like a beast to run. The mechanics for the depth crawl are not very well explained and I found myself having to go back and re-read sections 3-4 times to finally understand how to run it, and there were still parts that are confusing for me. For example when does a warden roll for an encounter and when do they roll for an event. It seems like these two tables can be interchangeable at time. Also there are no instructions, other than at a few locations, to roll an event, and on the event table there is an option that says roll an encounter. So it feels a little confused how exactly a warden rolls up a location/encounter/details. There also doesn't seem to be much guidance for the PCs. It was only after reading the entire adventure did I realize that the PCs can assault the Gorgon's Head at any time and that going into the different locations and destroying the pylon in each one just makes the Gorgon weaker. It is unclear how the PCs are supposed to know to do anything that the adventure wants. It also seems to me somewhat unwieldy with all of the different events and encounters but also the different factions and secret agendas, another thing that is somewhat unclear. Overall while I admire the scope and scale of this project it would definitely take some doing by the warden to get this adventure on the table. 

Theme: 2/5

I like that the ziggurat and Gorgon's Head is beneath the sands in a desert and that it is uncovered in an asteroid impact, and the way the adventure itself is a depth crawl so you are going down below the surface. Other than those two factors though I didn't really see much more playing off the theme of "Just Below the Surface". Maybe if the adventure had been a little more focused, like with one depth crawl instead of three, the theme could have been explored more. 

Overall I think this is an ambitious and great looking pamphlet that maybe fumbles the execution in some places, but I'm excited to see what else this team puts out.

Great Job!

No surprises here, this is stunning. Too bad there isn’t a six on all the ratings.
