Iron Crisis

Iron Crisis is an artificially manufactured shortage of iron in Sword Coast area created by Iron Throne and Sarevok Anchev. Iron Crisis was achieved by combination of 4 main elements:
 * poisoning iron and killing miners in Nashkel Mines
 * heightened activity of bandits achieved through cooperation of chill and Black Talons
 * rise of diplomatic tensions between Baldur's Gate and Amn
 * exploitation of Cloakwood Mines

Iron throne goal in it was monopolization of iron trade in in Baldur's Gate and surrounding areas through sabotaging of Nashkel Mines crippling trade in Sword Coast and providing from their secret mine in Cloakwood, while looming threat of war with Amn would cause iron demand to skyrocket.

Sarevok goal was destabilization of Baldur's Gate political elites through iron shortage, threat of war with Amn and replacing nobles with doppelgangers in order to get elected as head duke of Baldur's Gate. He would then use that position to start war with Amn which would help him achieve godhood through massive amount of death caused by it.
