Expedition to Undermountain
Centuries ago, Halaster Blackcloak and his seven apprentices established Halaster’s Hold and began exploring the dwarven delvings beneath the plateau. Of the Seven, one is known to be dead and two are known to still live — Trobriand the Metal Mage and Murial the Misshapen. In addition, in the years since Halaster claimed the Underhalls for his own, the Mad Mage has taken on additional apprentices, some of whom still stalk the depths of Undermountain.
In the Year of the Gauntlet (1369 DR), the events of Halaster’s Higharvestide upset the delicate status quo in the Underhalls of the Mad Mage. Among the tumultuous events of that day, Trobriand was attacked by his abandoned experiments and driven from his lair in a deep sublevel of Undermountain, and Muiral was expelled into the streets of Waterdeep by means of a malfunctioning portal. Trobriand convinced Muiral to return to the first level of Undermountain, where the madness-inducing magic of Undermountain was at its weakest.
There the two ex-apprentices forged an alliance, agreeing to work together to carve out a new domain largely beyond the reach of the Undermountain’s maddening taint, but sufficiently within Halaster’s Halls to allow them to continue to pursue their interests.
As word spread of a hidden arcanists’ academy located in the first level of Undermountain near the shaft to the Yawning Portal (C48), dozens of dark arcanists flocked to their service, drawn from across the North and the length of the Sword Coast.
