The Osmiri Empire
The Osmirian Empire appreciated their history, and thus would maintain old structures rather than building new ones over them. For this reason, Osmirian cities are made up of everything from single family Tree-Houses built into the canopy around and throughout their cities to great stone pyramids built into the center of their cities. Magic was prevalent and incredibly common to the Osmirian Empire, to the point that even commoners would have some degree of magical skill, even if just cantrips. They used magic to power their civilization with applications including transportation (trains and skyboats), manual labor (farming and building equipment), and law enforcement (lie detecting magic and a police force armed with wands.)
Though all races could be found in the Empire, the primary race was a species of owl-like humanoids called the osmi. Small settlements of the osmi can be found today in Myradon, mostly in Leamas and Tabeth, whose forests are similar to their ancestral homeland of Astaria. Although much of the history of the Osmirian empire has been lost to the ages, the Osmi do still tell the story of the one-eyed cataclysm which destroyed their homeland.
