Explorable area

An adventure zone is your party's very own instance of the game world. Adventure zones are where most of the PvE content takes place (the other being  Missions.)   Mobs in adventure zones are typically geared for a certain  level of player.

Getting to adventure zones
To get to an adventure zone, you simply leave the city or  outpost you're in by walking through the zonepoint. There will be a sign near the zonepoint indicating which zone this exit leads to.

Quests
All quests take place in or through adventure zones.
