Prior to the arrival of humanity, the duchy of Vulyar was simply the northern edge of halfling habitation in Khorvaire. Scattered goblinoid communities dotted the landscape but remained separate from the nomadic patterns of the halfling tribes; no known archaeological evidence suggests the two groups intermingled. The expansion of humanity east of Scions Sound disrupted these communities, until eventually Karrn butchered the goblinoids and drove them out of Karrnath entirely. While the halflings were not subject to the same genocidal campaign as the goblins, they were nonetheless forced south by the encroaching human kingdoms.
Human habitation has always been contingent on the viability of sedentary agriculture; communities that push too far south would eventually disband in the face of the arid plains that cannot support their lifestyle. Throughout the years some individuals have joined with the halflings, but halflings far more commonly abandoned the nomadic ways of the plains for the material wealth promised by Karrnath, either as mercenaries for the fledgling House Deneith or through the houses Ghallanda and Jorasco.
Shortly after Galifar I’s reign over the continent began, the Talenta Plains were formally included in the Kingdom of Galifar. The duchy of Vulyar was made responsible for collecting taxes and tribute of the nomadic halflings, who had no fixed towns to govern. This arrangement worked well enough, as the halfling tribes carefully concealed their wealth to avoid the avaricious gaze of empire, revealing just enough to remove suspicion. The settlements of Vulyar remained as they always had, scattered agrarian communities living in the ‘good enough’ soils south of Vedykar.
The Last War transformed Vulyar; not only did the tribute of the halfling tribes dry up, but the long border along the Cyre River became a key point of contention. Many battles were fought in the duchy, as the Karrnathi military pushed into Cyre or was pushed back. The halfling tribes cut deals with Cyre, Karrnath, and later the elves of Valenar, pledging their support in both trade and politics.
Today, the elves of Valenar are the duchy’s chief concern, even more than its long border with the Mournland. Constant raids by Valaes Tairn warbands disrupt attempts to rebuild in the wake of the war, but these raids are more intended to draw out a military response than about doing lasting damage.
