The Lost Castle of the West

The baron of Mercy's Hazard is investigating a series of murders in the neighboring viscountcy, when something very unexpected happens.  The entire castle town and its residents are transported to another world. A world that is slowly killing them, unless they can learn to harness its strange magics.

At least the army of orcs that was invading got scattered to the wind in the process.

That's a good thing, right?
