I have been making monsters for a new game I'm working on, The Nightmares Underneath. It's old school style dungeoncrawling but with dungeons that are extraplanar incursions made of nightmares (and with a vague setting that's more Middle Eastern/swords and sandals than Euro-American fantasy forestland).
So I thought if all y'all were interested, I could post them here, as a bonus thing (much like the extra dungeons). The rules are compatible with Labyrinth Lord but not Dungeon World, so you'd have to do your own conversion if that's what you're playing.
And also, they probably won't be illustrated by Nathan, unless some of them make the jump from this game over to our Monthly Monster projects (the iridescent globes were originally written for this game, and then I added them to the skinwearers).
