From publisher blurb:
Dan and Pau. the Wandering DMs, set themselves up with the challenge of stocking an entire dungeon in under two hours on their weekly live stream. What you see here is the output - a one page dungeon style adventure through an ancient monestary that has been long neglected and ravaged by nature. It features a sentient extraplanar ooze and a group of deranged warriors who worship it as their slimy overlord!
This product was made freely available to all patrons of the Wandering DMs, and is also available here for individual purchase. You can watch Dan and Paul create this very product live on their YouTube channel, Wandering DMs, in Season 03 Episodes 34 and 36. And while you're there why not enjoy one of the many other episodes featuring thoughtful discussion on D&D and other TTRPG related topics, as well as interviews with various luminaries of the RPG space. Or watch one of their many actual play episodes of old school D&D, Warhammer, and more.
