Strix

The Strix are a race of winged people originally from the mountain valley that became the March of Alaterra in the Kingdom of Mir. Extremely insular, they're still rare outside of Galeir and, while considered citizens of Mir and able to freely traverse the nation and join wider Mirran society, are known to never lead their own isolated communities nestled deep within the cliffs and hills of the Altidore Mountain Range. Wanderer Strix that don't return to Galeir often settle in Calaim, the most welcoming of the viceroyalties to the less-humanoid members of Mirran society.
The Strix are bellicose and fierce, stick strongly to their traditions, and do not forget easily. Strix communities are allowed to operate with their own laws and culture, so long as they are kept private to the community itself. Some hamlets and towns in the north of Alaterra are known to rely and trade with the local Strix communities more than with the local nobility - and the Strix of Alaterra also enforce most of the cultural bans on accessing certain locations considered sacred in Alaterran tradition. This has been the status quo since before the city-state of Galera became the viceroyalty of Galeir - and some of the few surviving records of the time suggest not even the mighty Empire of Palanq was able to subdue the Strix.
With Strix already being rare outside of Galeir, they're completely nonexistent outside of Mir proper.
