10^th Siege of Bruh Gevul

A battle of the First Dragon Wake (218 GE - 235 GE), it saw the forces of Tiamat besieging a citadel named Bruh Gevul. The tenth siege, it again saw the attackers driven back by deadly missile fire.

A fire giant warlock, one that had learned his arts under Orcus, came up with a plan to destroy the Foghorn of Talos. As part of the ritual, this warlock sacrificed a captured gold dragon, then had a half-son of Surtur shatter the horn with an equally powerful item called the Heel of Geb. When the Foghorn of Talos was broken, a permanent fog engulfed the valley of Bruh Donin. Tiamat's army was wiped out in that fog. In her war journals, found in most of her temples, Tiamat says she should never have trusted that wily warlock.
