Maerimydra

Maerimydra is a large drow city located below the Dalelands in the Deep Wastes.

History
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.

When the Silence of Lolth began in 1372 on 28 Elesias, it caused growing unrest among the Drow, until the city's archmage, Duneth Wharreil, used the confusion to launch a coup on the remaining houses. On 23 Eleint, the city was sacked by the half-fiend Kurgoth Hellspawn and his army of goblins, ogres, fire giants and demons. Most of the drow inhabitants of the city were killed or enslaved, with some escaping into the surrounding Deep Wastes. The single drow house to survive with any assets was House Dhuurniv, because most of them lay outside Maerimydra.

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.

Modern Times
Lost in religious war during a period when Lolth was silent to her followers, Maerimydra was once the greatest drow city of the region. A powerful priestess of the drow goddess of the undead (who was slain by Lolth long ago) seized the city, aided by goblins and fire giants.

Fire rules supreme in Maerimydra now. Giants have cemented their control under their queen, the fire titan Hledh. The giants and their servants have rebuilt most of the city to proportionate size and expanded the vault in which it was built. Azers and hell hounds patrol the nearby Underdark, and the giants keep hundreds of drow as slaves.

One needn’t go to Maerimydra proper to find giants. All the outposts that once policed the surrounding Underdark are also under the control of Hledh’s clan. Her territory secure, Hledh might start to ponder whether she can succeed in conquering part of the Dalelands.
