Nightmares of the Last War
Adar is the mountainous region southeast of Riedra, and east of Syrkarn. It is inhabited mostly by humans (including the kalashtar), though there is a prominent contingent of dragons on the uppermost peaks.
To its inhabitants, Adar is mostly known as a refuge from the dictatorship of Riedra, and many of its residents can trace their lineage to refugees and dissidents of the Riedran state. To this day, Riedra considers Adar a danger to its enforced stability, and regularly sends troops to attack the borders of the region.
