The Ferdiad Cycle
Mynydd-Brynn, located north of Aenoria, are the tallest mountains in the eastern Drystan. They were risen from the ground in one day by the cataclysm known as the Skyfall at the end of the Imperial Cycle. It is a mystical area populated by many monsters and Greenskins tunneling underneath it’s peaks. While no nation claims ownership over it, the Bridei consider it a holy place and exterminate any outsider who dares to enter.
In 1097 explorers discovered fountains in the southern mountainsides that seemed to have healing abilities, later dubbed as the Godspring. Three years later the prophet Tios mac Larwein built the Larwein temples into to guard the holy fountains, launching the Bridei into a holy war that has lasted to this day.
