Maerimydra

Maerimydra is a large drow city located below the Dalelands in the Deep Wastes. In 714 DR, in the wake of the fall of Myth Drannor the city conquered what was to be Shadowdale. They ruled it for nearly 200 years until 906 DR when the water wizard Ashaba drove the invaders out of the Twisted Tower.

The city has been relatively quiet ever since. The Silence of Lolth changed this. At first there was just unrest but then the city's archmage Duneth Wharreil became ambitious. He weakened the city and as a result the city was sacked by the half-fiend Kurgoth Hellspawn and his army of goblins, ogres, fire giants and demons. While the mage and Kurgoth's army were destroying the city's strongholds the local cult of Kiaransalee took over Castle Maerimydra, the home of House Chûmavh which, at the time was the ruling house. The leader of the cult, an albino drow named Irae T'sarran killed Duneth and, under her god's direction summoned Kiaransalee's Undying Temple to the Prime Material Plane. She in now concerned with using the temple's negative energy to research a new spell that will raise all of the corpses in and around the city simultaneously as a singular horde of powerful undead all under her command.

A few small bands of Drow refugees fled the sacking of the city. One party managed to travel the 100 miles to Szith Morcane, an old outpost of Maerimydra. The Lolth-worshiping leaders were slain by Irae's two children who then organized raids on Daggerdale.
