The events of EverQuest Online Adventures take place 500 years before those of the original EverQuest game. Battles, cave exploring, and loot gathering all contribute to the players writing their narratives and history.
There are five continents, Odus, Tunaria (the past before Antonica, as the Elves are just beginning to leave the world), Faydwer, Kunark, and Velious, as well as alternate planes of existence and the moon Luclin, all of which can be explored. However, some locations can only be accessed once a character reaches a certain experience level.
Depending on their classes, players will get critical tasks to fulfill from non-playable characters (NPCs). Players can also finish their jobs by working with other players or against them, either cooperatively or competitively.
