Indeed, tomorrow is EverQuest's 14th anniversary, and SOE is kicking off the celebrations a day early. New anniversary missions that were designed at 2012's SOE Live are now active, as is all of the previous anniversary content. Double XP is also in effect to give your characters a boost.
The developers released a few fun facts about EverQuest for its anniversary, including that the number of NPCs (344,935) is more than how many people live in Tampa Florida. Also, if you created a character on launch day in 1999, then according to Norrath time, that character would be 280 years old.
