Good work, especially because you only used 3 of the 4 pages. I particularly like your first page. I feel like your tagline under your title is strong, the map is great. I really like the hand drawn look. The adventure synopsis is a nice touch.
On the second page, you start to dive into specifics. I feel like a little bit more clarity in character names would help. Orphea is named in the bullet point after the character is first directly discussed, which made me double back and reread to make sure I wasn't missing who Orphea was supposed to be. I had the same issue with Seelia and Senara, who I'm assuming are Oren's younger sister and advisor (though I don't know which is which). The second one is a little bit tougher though because the two don't get referenced as a pair until the third page, though Seelia does come up in the second Adventure Hook. I think polishing up the text to make sure that character names are provided when those characters are introduced would go a long way to helping readers understand the module on a first pass. If I were to point to one thing that you could use your 4th page for, it would be something to help identify characters by name and give some more detail on who they are and how they act.
If I'm understanding the third page correctly, the Blessed Ruins is the current location of Senara, Seelia, and Orphea and therefore, the ultimate destination for the adventure. It is just a little bit unclear. On my first read, I assumed that the haphazard camp was evidence that they had been there, but not that they were still there. The light shining through the roof is the hint that tells me they're still there. I do think that if this is the case, it could be made more clear. I had the thought that maybe the system had a procedural solution to determining if the hexcrawl is over though, so I wasn't sure if the lack of specificity was intentional. I ended up reading through the Cairn hexcrawl procedures just to make sure that wasn't the case before going back and rereading it.
All in all, I really like the submission. I like how much effort you put into specifying the world that the players are in. I think that's really true to form, and something that I'm now kicking myself for not doing as much of. I also absolutely need to add a better intro written in prose rather than game speak.
