EverQuest Online Adventures is set five hundred years before the original EverQuest. Players create their own story and history through battles, exploration and cave hunting.

Five continents, Odus, Tunaria (the past before Antonica, as the Elves are just beginning to leave the world), Faydwer, Kunark, and Velious, the moon Luclin, and alternate planes of existence are available to explore, although some can only be reached after a character achieves a certain level of experience.

Non-playable characters (NPCs) will give players main quests to complete, depending on their specific classes. Players can also complete their own quests cooperating with other players or working against them.
