The capitol city of Xenogaea, Polomos City, named after the Polomos River (Xenogaean: /po̞.ˈɬo̞.mo̞ʂ/, also spelled Polómos), a tributary of the larger and more well-known Mourŷnkeidar (Xenogaean: /ˈmo:.rɨ̞.ˈᵑke:.dəɾ/, also spelled Móúrŷnkéídar), is the largest city in Xenogaea by both area and population density, boasting a whopping 42 million people living in an area of around 17,000 square kilometers, housing roughly 8% of the entire population of the country in its northernmost corner. It also appears to be the oldest continually-inhabited urban center in Xenogaea, with surveys of the land indicating settlements submerged under the rest of the city may date back as far as 14,000 years ago, with some even more scant evidence suggesting the city may be even older by another couple millennia. As such, it is also highly important to reconstructing early Xenogaean history. Despite arguably being the most historically important city in the region, it is a common misconception that the Xenogaean royal family's palace is located here: though the family owns a so-called "summer palace" here, the main palace is actually located in the city of Ndoskani (Xenogaean: /ˈⁿdo.ska.ni/, also spelled Ndóskani) in the country's Isanunti mountain range. Like many cities throughout the country, Polomos City is heavily fortified to keep out indigenous megafauna, making use of infrasonic cannons oriented along a ring of outposts to drive away wandering dinosaurs. If, however, a stray dinosaur does manage to wander within range of the city walls, guards are placed there to sedate, immobilize, and transport it to a safer location. In years past, megafauna which wandered into city walls were killed on sight due to fear of danger to the public, though as many species in the region are now heavily endangered, such protocols were revoked in favor of a "catch-and-release" method. Despite its status as the capitol system and the center of lawmaking in the country, Polomos City is infamous for its rampant petty and organized crime alike, something which the city's police department has frequently been accused of either enabling or directly engaging in themselves. As such, it's often referred to "Xenogaea's bloodiest city" or "Xenogaea's dirtiest city" (though ironically, it's actually ranked 1st place for the cleanest city countrywide).
