Wintergrasp is a large zone located between the Sholazar Basin, Borean Tundra, Dragonblight, and Icecrown. Wintergrasp appears in the second World of Warcraft expansion as the first non-battleground zone fully dedicated to world PvP, even on PvE servers. It focuses on siege weapon warfare. You can purchase Wintergrasp honor rewards from vendors that appear when your faction controls the zone.
