Nagrand

Nagrand is a Burning Crusade Zone located in Outland. It lies south of Zangarmarsh, west of Terokkar Forest, and southwest of Hellfire Peninsula. It is the last remaining unscarred region of Outland.
In the center of the zone is the neutral town of Halaa, which can be captured by either faction. Whoever holds it will have access to a mass of amenities including active quest givers, NPCs who accept turn-ins acquired from the zone's monsters, vendors, trainers and the like. The opposing faction, naturally, is locked out of all this, which is precisely why they will be laying siege to it around the clock.
