Map of Heran, 18th CSR

Heran /hɛ'ræn/ was the name given to much of northern Tarnaria between the 13th CSR and 2nd CTR. Heran was bounded by the Gratfeef river in the east, by the Erna river in the west and by Toyen in the south. Whether to consider Laeooy Coast and Commonground part of Heran is debated, as people from those areas were generally considered to be foreigners in Mantar or Tonaran, but at the same time economically the region was far more united than would appear from the cultural clash.
