Mantol-Derith

Mantol-Derith was a trading city situated in an underground cavern three miles below the surface.

Geography
Its exact location was not known by many. It was located on the shores of the Darklake, on the other side of which was the duergar city of Gracklstugh. The nearest drow settlement was Menzoberranzan, or Ched Nasad before that city's destruction.

Structure
Mantol-Derith was located in a twisted cavern 60–70 feet tall and twice as wide. The city was heavily guarded and protected by strong magic. The cavern was naturally formed by water because of its proximity to the Darklake, and was filled with waterfalls, pools, and streams. Its walls were filled with multicolored crystals and gems. Bridges across the various streams were carved from crystal. The city itself primarily comprised trade caravans and campsites.

History
In 1372 DR, the city was was very quiet because of the problems during the Silence of Lolth in Menzoberranzan and elsewhere. The drow group led by Quenthel Baenre stayed here while they worked to gain access to Gracklstugh across the Darklake.

Inhabitants
It had small groups of merchants of many races: drow, illithid, svirfneblin, and duergar. Bugbear mercenaries were often spotted there.
