The Retribution Crusade
A giant rune-carved adamantium pillar in the underdark. It is said that at the dawn of the world Moradin made a pact with the earth elementals to create this magical ward on the border of the elemental plain of fire. He charged the Redcrown Clan with the sacred task of guarding it. Now this charge rests on Thane Terrinn Goldenbeard.
Recently it was taken by fire giants under the command of Tori Muspelwalker.
