Those who squint long enough through Mount Irem's blinding snow storms can see lights flickering high on its slopes. The people in the town below tell stories of a castle made of ice that glimmers at the high end of Tharg's run, but, when the weather is clear, no trace of it can ever be found. If it exists at all, it seems to exist only in the storm.

Snow is designed specifically for 5th - 7th level parties (depending on group size, magic items, all that) in Peryton RPG, Basic Fantasy RPG, and Labyrinth Lord, and should be easy to adapt to similar systems. Stats are also provided for Tunnels and Trolls. The T&T monster ratings in this adventure mostly range from 50 - 150. (Note for T&T players: several of the encounter tables use dice other than six-siders.)

It includes several new monsters and unique hazards in addition to the scenario, but this is still just a quick one-shot adventure of the sort you'd play at a convention.
