The Foramere Basin was a low-elevation region in central Tal'Dorei where water from two rivers came together in a giant lake before draining into the Lucidian Ocean. One river flowed from the Cliffkeep Mountains in the northwest, and the other from the Stormcrest Mountains in the south. The Foramere Basin itself was located south of Westruun, north of the Frostweald, and southwest of Kymal.
After the Chroma Conclave attacked Tal'Dorei and Westruun was overtaken by Umbrasyl and Kevdak's roving band of barbarians, many of Westruun's citizens fled the area. While some refugees were welcomed into Kymal, many were turned away due to the sheer number of people displaced. Those people travelled to the Foramere Basin and established an encampment.
