The cover image is evocative. Even though you squeeze it into a mere quarter page, you include all the important cover info, and save your page real estate for the text of the adventure.
This is probably the most economical use of space I have seen in the jam. Yours is one of the entries with the most words: you even have room for the luxury of read-aloud text. The adventure is very clearly laid out, with judicious choice of fonts, colours, boxed text. The clear and attractive page layouts will increase playability at the table.
At first glance, the setup is a classic quest: break the curse, find the treasure. But the additional requirement to learn Ser Koschel’s story adds narrative and role-play elements. I like that the story is revealed piece-by-piece through player interaction as the adventure progresses.
The adventure is presented as a series of atmospheric locations, with random hazards and three repeating encounters. The fixed order of revealing Things Known means that the narrative will be progressively revealed. This looks like an entertaining night’s play, with plenty to keep the party engaged. Nice work!
Minor nit-picks:
In the “spreads” layout, shouldn’t the first page be on the right-hand side of the A4 spread, so it is the front cover when folded?
The factions are listed in a different order on p.1 than on the back page. (It adds a little unnecessary cognitive load to match them up.)
Typo on p.1 “amiral” → “amoral”
