 **Field Descriptions**
 
@@ -64,9 +68,21 @@ The ID of the [template](creature_template#creature_template-entry) that is used
 
 The ID of the [map](Map) that the creature is spawned on.
 
+### zoneId
+
+The ID of the zone that the creature is spawned in. (e.g. The Barrens)
+
+This column is filled in by the worldserver on startup if the `Calculate.Creature.Zone.Area.Data` setting is enabled. It originates from AreaTable.dbc.
+
+### areaId
+
+The ID of the area that the creature is spawned in. You can think of an area as a "subzone" of a zone, e.g. Lushwater Oasis inside The Barrens. 
+
+This column is filled in by the worldserver on startup if the `Calculate.Creature.Zone.Area.Data` setting is enabled. It originates from AreaTable.dbc.

 ### spawnMask
 
-Controls under which difficulties the creature is spawned. The values are bit-masked, so you can add them together to combine the affects of two or more values.
