Aglarond was a magocratic state in the southwestern-most part of the Unapproachable East with its capital at Veltalar. Most of its land was covered by the Yuirwood. Filled with magic and mystery, it was ruled by one of the most potent spellcasters of the Realms: the Simbul, until 1425 DR, the Year of Seven Sisters, and as of 1475 DR was ruled by fifteen Simbarch of Aglarond — arcane spellcasters trained in the Simbul’s arts.
Aglarond’s isolation and its long history of sieges by Thay made the once-trusting Aglarondan people suspicious of outlanders – anyone could be an agent of their hated enemy. Aglarond was separated from the rest of Faerûn by the plateau of Thay to the east, and the Sea of Fallen Stars on the three other sides. The lands beyond the fortress at Undumor to the Thayan borders were beyond the direct protection of the armies of Aglarond and were thinly populated for this reason.
The Pirate Isles lay only a hundred miles or so off Aglarond’s own western islands, but since piracy was punishable by immediate execution in Aglarond, most buccaneers gave the land a wide berth. The length of water that separated Aglarond from Thesk was known as the Sea of Dlurg. This was more of a bay than a proper sea: At its narrowest point, about midway down its length, only fifteen miles separated the city of Furthinghome from the Theskian shore.
There was only one major port in Aglarond, Velprintalar, later known as Veltalar. The large peninsula’s coastline was mainly comprised of rocky cliffs with villages and towns settled near inlets suitable only for fishing boats and other smaller ships.
While the fey-dominated Yuirwood covered much of Aglarond, the land between the trees and the shore consisted of fertile, rolling hills that made excellent farmland. Farms were rarely more than ten miles from the shore. The half-elves who made their home under the Yuirwood’s leafy canopy discouraged large-scaled settlements of the forest with a mixture of compromise, diplomacy, and the occasional veiled threat. Despite such efforts, though, the woods continued to recede every year. Grasses, shrubs, and vines quickly reclaimed abandoned farmsteads, but trees were slow to return to territory stripped from the Yuirwood long ago.
As of 1479 DR, the Yuirwood was filled with plaguelands formed in the wake of the Spellplague, filled with ruins of an ancient, long-gone eladrin civilization.
Although Aglarond was at roughly the same latitude as Cormyr, its weather was much more moderate. The waters moderated the weather, so the seasons were rarely as harsh as they were elsewhere.
