I really like one page dungeons. My current campaign started with Andrew Harshman's one pager... and it sparked almost a year of play so far. One page dungeons are great for one-shots, drop in locations or even just a source to steal from.
So when the 2020 contest came up, I decided to write my own. I thoroughly play tested it... once... but it ended up being really fun (isn't it always fun to kill your players' characters?) and it now too, plays a large part in my current campaign.
Anyway, here 'tis... let me know if you end up running it!
