History
The vast underground dungeon that eventually became Undermountain was originally a stronghold and mine built by dwarves. When a shield dwarf named Melair discovered a vein of mithral beneath Mount Waterdeep in -1288 DR, he sent out a call to his kindred. Those who answered became Clan Melairkyn, and Melair became their king. Together they began construction on the Underhalls of Melairbode.

Around -750 DR, a group of Netherese wizards known as the Sargauth Enclave took up residence in an unexcavated section on the third level of the Underhalls. When Netheril fell several centuries later, the Enclave was mostly destroyed in the process. The few twisted survivors of the Enclave's destruction turned into powerful undead, becoming known as the Skulls of Skullport.

Beginning in -677 DR, the Underhalls of Melairbode were subjected to numerous incursions by drow from the city of Karsoluthiyl. After centuries of bitter fighting that saw the Melairkyn retreat ever deeper into the Underhalls, the dwarven clan was finally defeated by the drow in 211 DR. The dark elves named their conquest Kyorlamshin, and laid claim to most of the Underhalls.
