City of Glass
Note: this article is a work in progress.
The City of Glass is a large city located on an island in the southeast of the Central Continent of Qail. All you can see when you are approaching it is a part of the island with a giant half sphere sitting on it.
The whole city is surrounded by a magic shield, that blocks anything from going through from either side. The only way to cross it is wearing a true item of the creators.
