From Humble Beginnings...
Seven Pillared Hall
The heart of Thunderspire’s upper level is the Seven Pillared Hall. Dozens of lanterns hang from the walls and the thick pillars of this great chamber. The chamber walls have been fashioned in to building facades, so the Hall appears more like a city square than an underground cavern. Merchants conduct business in the Hall, at the behest and with the permission of the Mages of Saruun.
The Seven Pillared Hall, a mighty chamber, was once the market square and meeting place of the ancient undermountain city of Saruun Khel. In some ways, it still serves as a market and meeting place of sorts, but for a different kind of inhabitant. Today, the Mages of Saruun provide order and safety within the Hall, chiefly so that they can trade with the intelligent monster races that live within the Labyrinth and the Underdark beyond. While the mages seek to acquire goods and items important to their arcane experiments from creatures that normally don’t conduct trade with the surface dwellers, the relative safety of the place has given rise to an underground market – both figuratively and literally.
