Kair

A Kair (pl. Kairen) is a governmental subdivision of the Lein Empire, each of which is administered by a Kairadasti. It is the top level of the Empire's subdivisions, over the Meroye and Belir, but it does not in fact have a role in regional governance; rather, a Kair serves as the regional headquarters for central offices, and is primarily an agency to oversee regional governors and coordinate responses on major issues.

Structure and Functions
Every Kair has a headquarters, which most often is the seat of a constituent meroye. This headquarters serves as the regional base for governmental agencies which operate from the Imperial Capital; therefore the branch offices of the Imperial Secretariat and Imperial Commissariat would be placed therein.
