Wormwrithings

The Wormwrithingswere a series of twisting tunnels located to the north and west of Blingdenstone. Believed to have been created by a colony of purple worms, it is was later the home of many small tribes of kobolds who were beset by many larger predators. Before the drow attack on their city, the svirfneblin of Blingdenstone used to track the purple worms still living in the area as their excretions often contained precious metals and stones. Due to their racial enmity, the gnomes and kobolds often came into conflict as well.

Some believe that there is a connection between the Wormwrithings and the surface since the Urlbluk kobold tribe that lives by the headwaters of the Goblintide River are ruled by the same matriarchal system that the various tribes of the Wormwrithings are. Somewhere in the Wormwrithings was a magic portal that connected to a series of tunnels beneath the city of Waterdeep. Later known as the Fireplace Level, these tunnels were originally created by House Goth for their trade endeavors, but were abandoned and sealed up sometime around 1308 DR after a purple worm made its way through the portal into the them. In 1341 DR the Company of Crazed Venturers and Khelben Arunsun rediscovered the Fireplace Level, the purple worm (frozen in a temporal stasis trap), and the portal. Khelben magically sealed the portal using a gate seal spell "for the security of the city".
