Pictured above: The general reaches of the secular authority of the Bishopric of Tairngire around 900 A.D.. Population density is generally very low, and spaces between settlements are often just "colored in".
Pictured above: The administrative divisions of the Bishopric of Tairngire. Pictured are the domains of the loyalist Companies, the Britonnic nobility, and the "island" Measctha clans around 900 A.D. Rivers form fairly effective boundaries, meaning there are relatively few artificial borders. The borders between the island Measctha clans are also fairly fluid, and shift from year to year; this is a general approximation of trends.
