The Gem Mine

A group of kobolds crept into the mine a few days ago, entering from the surface and forcing the miners to abandon their jobs. No one was killed, but the kobolds are too dangerous for the miners to deal with. A human miner went missing a few days before the kobolds showed up, prompting other miners to fear that a monster must have crawled up from the Underdark. Oarus thinks it's possible that the miner fell down the central shaft, which is deep enough that his body would never be found.
