Brudell

When the dwarves were chased out of the Endless Shifting Desert by Xythrymaus,
their path into the Obscurra Mountains led them to a paradise under the mountains where they built a city named
Brudell.

The gnomes of the rain forest later found their way to the city of Brudell and began to live and experiment with the dwarves.
Those gnomes founded the University which has become the most notable center of learning and knowledge in the world,
but its existence is only possible because of the dwarves' defensible and resilient city.
