DB/AreaTrigger

Defines certain areas on the map that presumably tell the server to fire a certain event. IE in BWL, telling the goblins around vael to run away is a trigger defined here. There are also misc triggers out in the middle of space which have 0 size, which are most likely used by the server for certain things. One such use could be remembering settings per instance (ie dracnoid colors in on Nef)?
