Sword of Wonder

From Introduction:

High in the mountains rests the small community of Allthrop. Situated in a forested valley, it rarely sees visitors from the outside save for a few merchants who make it a point to stop here. But within the heart of the city is rumored to lay agreat weapon for one who is true to the world.

The entrance to the gauntlet is within the city's well. Brief forays into the well over the years have revealed the existence of two doors. Only the uppermost door has been able to be opened; the lower door has resisted all attempts — magical and mundane — to open it. Likewise, spells that have been used in an attempt to breach the halls below the city (such as dimension door) have failed.
