The Spire of Mysterious Origin
The Spire is a structure composed of what may or may not be organic materials. It has similarities to a large spiral of coral, light-grey in hue, and rises up at least 800 to 1,000 feet. It is slightly slanted, and no discernible entrance can be seen from the outside.
It is a structure surrounded in such mystery that one would be hard pressed to find information about how to enter or what lies inside from even those who have spent their whole lives in Outer Spire. This does not stop adventurers from all around the world from coming to the city in order to find a way inside.
