The Unapproachable East—Aglarond, the Great Dale, Rashemen, Thay, and Thesk—has been described as “a distant land of proud barbarians, overgrown ruins, and dreadful wizardry.”
The history of the Unapproachable East is full of drama involving magic so powerful it moved mountains, the rise and fall of ancient empires at war, and invasions of hordes of horsemen, all happening on a vast landscape that stretched from the warm southern coast of Aglarond to the grinding ice of the Great Glacier, from the Sunrise Mountains west to the Sea of Fallen Stars.
Much magic, both world-spanning and relatively mundane, was created in the Unapproachable East, and is specific to the area. In addition, in Faerûn each area and culture has its own norms and dictates which govern and influence the development of magic and magic items.
