Welcome to Uhgramudd, you'll never find a more disgusting, remote, fly-ridden, swampy Hell than this. Get in, kill the Lizards, grab the loot, get out. Simple, right?
This is an introductory low-level adventure I use to get familiar with players I meet online, to see if our play styles clash in any way. So far, it has weeded out a few undesirables and scored a few keepers. I am quite satisfied with the layout and have run it multiple times, with slight variations for level/abilities of the player characters.
Mining in a certain area turns all exposed skin (maybe just parts that are actively disturbing the chemicals that cause the reaction) of the those doing the mining to a dark blue color. Will wear off taking as many years/days spent in the mine. ... meeting a party of blue-skinned humans armed with pick-axes etc. Strange disease? Demon offspring? Curse? If they meet only one ex-worker, they will very carefully listen to any stories he says, no matter if drunken or insane, or just makes up to get a beer.
