From itch.io:
While travelling beside an open cave, you meet a band of eleven gnomes. The gnomes appear travel-weary and forlorn, huddled around a small fire near the cave entrance. The eleven gnomes mumble amongst themselves, talking of doom and other dire things. They had been exploring the cave, searching for their ancestors’ crystal keep, when they were come upon by monsters of the deep! Their leader, Bingo, was slain, and with him their crystal key was lost. The gnomes ask that you venture into the cave and retrieve for them the crystal key, for it is theirs by ancestral right, not to be sullied by the hands of cavern things.
Sleeping on Damned Reptile Gods is a one-page adventure by James Millichamp, created for the Random Adventure Jam. In it, you will aid a band of gnomes and descend into the deepest caverns of the earth, meeting trolls, clay-things, and reptile gods along the way!
