An explorable area is an instanced area of the map. Each instance is only accessible by the party that started the instance. An instance is lost when the last player in the party leaves it.
Once in an explorable area, players can explore, kill mobs, or complete quests. Most outposts contain exits to explorable areas.
Unlike missions, you are automatically resurrected upon death at the nearest active resurrection shrine.
Because these areas are instanced, the set of NPCs and monsters may differ from time to time. Creature spawns will sometimes be regulated by quests, so going into an explorable area while trying to complete a different quest may result in a different collection of enemies.
