Lightspires are ancient elven structures, built in the days of the aeroliths to serve as guides for the flying cities. Though built around the world, the majority of lightspires are located in Brightmarch, the Laqto Jungle, and around the Gulf of Aserdus. Left to decay for millennia, today most lightspires lie in varying states of ruin.
Lightspires are tall structures, the largest reaching upwards of 400 ft into the air. To reach such monumental heights, each cylindrical lightspire widens significantly at its base to have a large foundation. Lightspires are primarily stone and metal buildings, constructed in significant parts by the material discarded in turning aeroliths into flying cities. Pieces of the lightspires were moved into place by elven aerotheurges, aided by the significant amounts of ansharite in the matter from which they were built.
Atop each lightspire sat large, polished ansharite mirrors. Arranged around a central, magical light source, these mirrors reflected and intensified the light enough that it could be seen more than a hundred miles away. These lights were watched by mages tasked to ensure they were never interrupted, a role that was considered to bring high distinction in elven society during the era of the aeroliths.
The city-state of Teshub still operates a functional lightspire. In the absence of the aeroliths, today the Teshub lightspire is used to provide a beacon for ships crossing the Gulf of Aserdus.
