Until just a century ago, Kosra was merely a small coastal duchy that was frequently traded between neighboring powers in their struggle for dominance. But in W. 284, a local noble came to power in Kosra, who quickly modernized the Kosran army and exploited the power vacuum created in the aftermath of the First War of the Round Table to the West to intervene in the stalemated Third Virgo-Benic War on the side of Benidel, invade and annex Virgos, then betray their ally Benidel and annex them as well, turning the crushed Virgos army to their side with promises of Benic territory. In the span of a decade, Kosra had gone from a minor state to one of the preeminent world powers—as such, the Duke proclaimed himself Yhon I of House Kos, King of Kosra, and lowered Virgos and Benidel to duchies within his realm. His son, Yhon II, succeeded in creating a constitutionally absolute monarchy, with all powers ultimately reserved to the King of Kosra, his despotism also created strong revolutionary sentiment in Benidel, which persists to this day. The current monarch is Yhon IV Kos, widely known as Yhon the Drought, the Drought King, or simply the Drought, a moniker gained from his harsh economic policies, which are widely blamed for the poverty and famine that have spread through Bendel.
Population 24 million, 78% human, 8% Halfling, 5% Elven, 9% other; 5 million live in the original Kos territory, 12 in Virgos, and 9 in Benidel. Kosra has some of the only permanent Planetouched and Dragonborn settlements on the continent near the northern border, in the Kholmark.
