Unapproachable East is a hardcover accessory for the 3rd edition of the Dungeons & Dragons fantasy role-playing game.
Unapproachable East describes locations such as Aglarond, Rashemen, and Thay for the Forgotten Realms setting.
Unapproachable East was published in May 2003, and was designed by Richard Baker, Matt Forbeck, and Sean K. Reynolds.
As I recall, Sean turned in his chapter on Rashemen first, which was a great model for me to follow.
Then Rich took what we'd turned in, added a ton of his own material, and polished the whole thing to a mirror finish.
