If you want to use dnd 5e sandy Peterson did a couple adventures and a base ruleset called Cuthulhu Mythos. Theyre a lot of fun and totally built around suspense. Page 70 starts the chapter where they review insanity and dread. I love the dread mechanic.
Also, what do I do with all these skill gems?
Not much in 5e. Maybe cr 3 for the whole thing. A party of lvl 1 could do it assuming they don't roll bad on saving throws for the traps. The wasp and glass part seems most dangeous. If party is likely to just bum rush it, maybe cr4 and a party of level 2
Used to be a new rome too. Maybe those don't get counted though.
Just funny that a sodbuster is on the board (although tons of sodbusters on boards here in the Midwest usa). I don't think you're missing anything. It's just irreverent silliness.

Midjourney. I start with all the lyrics and then I use they syntaxes to give certain things weight to help ppl guess correctly
this is a good hint. the lyric is from the first line of the second verse
a phrase that may mean "tumbling?"
you are very close.... but not correct. i'll post some more hints below
