Filion'lyr

On a ridge above the Vuzlyn river, the settlement of Filion'lyr was founded by drow refugees. Once home to the world of Kriav, these former Thiliorúth citizens escaped by way of a feywild fuse, starting a new Drow civilization on the world of Bal-Kriav. From Filion'lyr, many holds would be founded across the surrounding subterranean regions and along the Great Tradeway.

At the northern tip of the city is a great falls and intricate lock system named The Mandible. In the city's last war with the aboleth, it was used in draining a great lake of the Caverns of Hlat'tar. The lake's draining brought an end to that area's two aboleth city-states, and centuries of economic strain and conflict.

Filion'lyr is home to the Sisters of Baalzebul. This ancient all-female order was the backbone of the Chari'they Alliance. Highly respected and feared, they are the reason the Church of Baalzebul is allowed to exist in the empire; that without them would be a monotheism to Lolth.
