Sé

Sé is the most-populous city of the province of Ryanby and is the capital of its namesake Sé Autonomous Region. The city has 30.7 million people, and there are over 50 million in the Sé Autonomous Region. Sé is a major anchor of the Lake Adimoore Extended Metropolitan Area (LAEMA) with over 180 million residents (2019). It is the second largest city in Eastern Delongo, and the fourth largest city in the nation and the world. Sé is situated on the confluence of the River Balatazana and the Adimoore River, at the base of Lake Adimoore, which is the largest lake in New Adimoore and Ryanby.

Sé was first settled by non-Indigenous populations in the early 20th century as a city for the small Spanish-speaking population of the Urban Matewood Area. In the 1950s it was decided by the Ryanby Government, headquartered in Oilman, that Sé would become an autonomous region. Ryanby had extremely limited powers in Sé, as it was a small government and Sé was a large city. At the time, Sé benefitted from its proximity to Matewood, but was mostly growing independently. Rosécia, the city located adjacent to Sé, benefitted most from its proximity to Matewood.

Boroughs
Like many major Delongonian cities, municipal powers are shared between the city government and the smaller borough governments.

The Gran Centro Service is an amalgamated borough structure designed to serve the needs of the central boroughs of Sé. It consists of the boroughs of Centro, Arganzuela-Malasaña, Iberia-Lagos, San Pedro Cholul, Potosi-Dora-El Puerto, Engátiva, and México. It serves a combined 4.4 million persons. Most services (garbage collection, recycling collection, snow services, road cleaning, etc.) are operated from Dora, the industrial core of the region.

Likewise, Atabanza, Rodriguez, and Gonrosa have combined many of their borough services, as have Cartagena, La Condesa, and Los Guayos.
