Some very cool ideas. I enjoyed the cat-summoning lock on the spellbook. Much more interesting than simply finding a book.

I would have liked a very brief introduction to give me some idea of that kind of dungeon to picture. Getting straight to the point is great, but a high level overview of what and where this dungeon is would be nice.

I think all the mysterious, magical stuff in the dungeon would make for a very enjoyable old-school dungeon crawl.

I feel like I could pick up and run this dungeon right away.  Good room descriptions, good use of traps and puzzles.  I think the one thing I was missing was bit in the way of introduction, was the nature of the dungeon meant to be open ended?

Great to see elves being weird otherworldly creatures instead of just people with pointy ears! I love the little ritual details, like the Path of Darkness - a temple that actually feels like it was used for some kind of worship! (Weird, otherworldly elfin worship!)

A classic dungeon crawl. My favorite part is the room with the skeletons chained to the wall with a 10' chain around their necks. That's a fun mental image.

Straight forward, concise, and classic! This would feel right at home at any fantasy dungeon crawling table.
