Tahvaair

Tahvaair, to the west of Ta'Araen, is ruled by an unknown number of ahvaiyru families; all non-ahvaiyru in Tahvaair are slaves of one clan or another.  These clans are known to feud amongst themselves in a manner said to be all the more vicious for being so genteel.  

Of more concern to outsiders, however, are regular sorties against neighboring Ta'Araen, by the ahvaiyru and their feiyin janissaries, in attempts to annex parts of it.  As diplomatic relations and legitimate trade with Tahvaair are nonexistent, little else is known.

Ta'Araen

Ta'Araen is the most diverse, and in many ways the most cosmopolitan, nation in the Tirin Peninsula.   Most of its human denizens are the descendants of several different tribes known collectively as Tirins, and the vestiges of many distinct cultures still survive.  

Approximately half of the nation—centered roughly around the capital, Araenkeep—is given over to farming.  Further south, along the border mountains that separate the peninsula from Dellumea, mining for various metals predominates.  The remainder of the nation is prairie and light forest.  Here, due to all-too-frequent attacks from Tahvaair, there are few settlements aside from military garrisons.

Kalretia

Kalretia (or, more formally, the Kalretian Archipelago) is located to the northeast of the Tirin Peninsula.  Its thirteen islands have approximately the same total area as Ta'Araen.

The true natives of the islands are apsuri and lizardfolk.  But in recent generations, humans from a northern continent have established a colony on the largest island.  As a result, two distinct major cultures have sprung up:  "Islanders," centered around the main seaport on the largest island, are primarily influenced by the human colonists; "swampers," denizens of the brackish swamps of the northeastern islands, are primarily influenced by the apsuri.
