Once home to a powerful nation of elves, in 1372 DR, the Yuirwood is the site of ancient ruins of unknown power and origin. It is located in the center of the nation of Aglarond, and is populated by elves and half elves. Sildëyuir is a plane of finite size that is conterminous with the Yuirwood in Faerûn, perhaps two to three hundred miles from end to end, and is home to the Star Elves, a subrace of elves that left Faerûn in antiquity. The ruins in the Yuirwood are the remnants of their original society.

In −9800 DR, the Yuirwood was settled by green elves in the aftermath of the Crown Wars. In −6950 DR, the star elves began leaving other elven nations and gathering in the Yuirwood. In −6600 DR, the star and green elves founded the realm of Yuireshanyaar in the Yuirwood. The human empire of Unther battled Yuireshanyaar in −1250 DR for control of the southern Aglarondan coast, and the Yuir were driven back into the woods. From −1076 to −1069 DR, the Orcgate Wars occurred after an Imaskari wizard opened up a gate in Mulhorand to the orc's home world, and Yuireshanyaar was pressed hard by the orcs. Faced with the encroaching humans along the Wizard's Reach (most from Old Unther), the star elf High Mages of Yuireshanyaar created a forest-wide network of stone circles and worked a mighty high magic spell through the stone menhirs to construct the extraplanar world of Sildëyuir from −900 to −600 DR. In −699 DR, the Year of Moon Blades Crashing, the star elves completely abandoned Yuireshanyaar for Sildëyuir, but many wild, or green, elves chose to remain in the Yuirwood. Araevin Teshurr and his companions visited Sildëyuir in 1374 DR, the Year of Lightning Storms.
