History of the Forgotten Realms

The Swordbelt Alliance sacks the subterranean city of Oaxatupa, scattering the tlincallis like a giant stepping on an anthill. In the years that follow, the stingers boil up to attack targets throughout Amn and Murannheim without warning, forcing the two neighbors to maintain their uneasy truce. Although the Armory of Nedeheim is never recovered, adventurers return from ruined Oaxatupa with reports of a portal to the Abyss from which demonic servitors of Obox-Ob continue to pour forth in support of the tlincallis. The Council of Six institutes a heavy war tax on Amn in preparation for years of warfare.
