EverQuest: The Legacy of Ykesha was the fifth expansion pack and only extension pack for EverQuest. It was the first EverQuest content expansion available almost exclusively from Sony Online's direct purchase and download service. After a while, Legacy of Ykesha was available in stores. Ykesha was released in February 2003 and was considered a minor content addition at the time. It was an experiment in the idea of "content extensions", but the idea of these micro-expansions never caught on.
