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.
Turning on either of these auras costs no mana and often frees up a slot in the bard's combat twist by filling in a buff role that would normally require singing a song. The downside to relying on auras in this way is that their range is very limited, often too small to cover the casters and healers they are intended to benefit. Also, when the aura buff does eventually end, it may take the bard a little while to notice that the icon has disappeared, depending on what he or she is paying attention to at the time. This can potentially lead to the group going for a long time without the benefits of the buff in question.
