Name: Mines of Kranak
Brief History: A long-abandoned mine that was once prized by the Dwarves for its rich ores. Recently, new veins of extremely rare materials were discovered, prompting an operation to resume mining immediately.
However, several mining teams have disappeared due to some unknown monster prowling the tunnels. Under normal circumstances, dwarven soldiers would clear out their own mines, but most of the local forces have been dispatched to route a monster infestation at the northern borders, necessitating that they get help from the outside (that's you guys)
It's imperative that the mines are cleared out quickly, as the resources are immensely valuable, and an unattended mine is ripe for thievery. In exchange for your services, the Dwarves are offering two sets of mithril armor to the party's specification as a reward- a small fortune.
Layout Summary: The entrance to the mine is located near the top of a remote mountain, and getting there is a perilous trek on its own.
The mine itself is a labyrinth filled with old mining equipment and smelters to create ingots of the materials within. Despite being decades or even centuries old, most of the equipment is still functional. Besides mining equipment, there are also living quarters due to the long periods of time miners would work here, containing beds, various facilities for entertainment, books pertaining mostly to practical crafts but also dwarven history and mythology, and even a functional tavern with casks of ale.
Valuable ores lie deep within the tunnels, but getting there and back is a fool's task without careful usage of navigational tools.
Interestingly, experiments with bioluminescent mushrooms have resulted in a type of lantern that doesn't produce smoke and makes light indefinitely; these are scattered along the walls of the mine, providing a surprising amount of light.
Threats(Enemies, Traps, etc): The trek up the side of the mountain will take approximately two days. Blistering winds and extreme cold demands that adventurers haul heavy clothing, rations, tents, and even firewood, as very little is available. Beyond the climate, hostile wildlife also prowls the mountainside, from wolves to bears and even worse.
Lastly, a lone monster is stalking the mine itself. Though little is known about it, it's dangerous enough to take down dwarven mining teams, strong men used to dealing with cave-ins and skirmishes with kobolds.
