In order to enter the expansion's basic zones, a player had to reach the former set planar level of 46. From there, one had to complete tasks to gain access to the more advanced zones. It was later changed so that once the character reached level 55 they gained access to two more zones which are the Plane of Valor and the Plane of Storms. At 62 the Bastion of Thunder then became available. Those level limits can be bypassed by completing the progression of the expansion, allowing for example to be level 46 while adventuring in the Bastion of Thunder. The maximum level was increased from 60 to 65 with this expansion and new Particle Weapons were added, when before only epic weapons had such visual effects.
The EverQuest universe is divided into more than five hundred zones.  These zones represent a wide variety of geographical features, including plains, oceans, cities, deserts, and other planes of existence. One of the most popular zones in the game is the Plane of Knowledge, one of the few zones in which all races and classes can coexist harmoniously without interference. The Plane of Knowledge is also home to portals to many other zones, including portals to other planes and to the outskirts of nearly every starting city.
