The state of Amn is under siege to the south, the High Moor is being overrun in the north, and the region around Baldur's Gate is in turmoil. In an area known for its ample resources, a crippling shortage is slowly developing for the metal that is used throughout the Realms for everything from swords to forks: iron. The armed factions in Baldur's Gate can scarcely keep themselves armed, and the commoners are suffering all the more. Without iron they cannot mend their tools or purchase plows--and if they cannot farm or craft, they will starve come winter. Some blame Amn for the chaos, others the trading cartels, and still others suspect even the Dukes of Baldur's Gate. Yet, this contagion may be an early omen of some greater evil.
It's up to the player to determine the machinations behind this struggle for power--and to prevent the war that threatens to engulf the region (or, if playing an evil character, to try and assume more power in the process). Throughout, your main character's origins are mysterious; your search for your identity has links in the game's planned sequels.
