Padun

Padun is a structure found within the Ba-Adenu Forest.

Background
Padun is an enormous oval-shaped wall, almost 15 miles across, deep in the Ba-Adenu Forest. The original structure seems to have been built from a soft metallic substance carved or shaped into round stones. Over the years, a variety of materials, including stronglass and purple trees from the Ausren Woods, have been used to extend and repair the wall.

Its surface features countless windows, doorways, holes, and other entry points. Some have been constructed and include doors that close and lock. Other entrances appear to be the remnants of wars, battles, and attacks.

A number of cities, fortresses, and strongholds have been built within the wall, but all failed and are now little more than ruins. For every potential ruler who sees the giant wall and imagines a kingdom of loyal and protected subjects, there's someone else who will take advantage of the difficulty in defending such a large structure and space.
