Love the cover (Space Skeletons! High five!). Like that the horn teleports adventurers from across time and space; you could throw this into an existing campaign as a palate cleanser or side quest. That helps it fit the Appendix N theme as well.
The dungeon is pretty basic but that's not a bad thing here (and it works logically with the story). Maybe a little more looping would be nice.
I like the monsters, and like that Gan has one of the magic items on him.
Overall, would print and keep in my binder of adventures!

Thank you! I’ve never done a cover like that, so I’m quite happy with how it turned out!
I’m hoping the dungeon has just enough head-scratching, backtracking, and tense Gan encounters to help it feel a little bigger in play than it is on the page, so if you end up running it someday, definitely let me know how it goes!
