The Buried Sea is the thirteenth expansion of the MMORPG EverQuest. The story in this expansion revolves around the sunken Combine city of Katta Castrum. This ancient city is the resting place of the incapacitated Tsaph Katta and is protected from the crushing depths by an ancient and mysterious energy field that has started to fail.
Players are treated to a number of new features including ship-to-ship combat, faction vendors, a number of new raid zones and new armor mechanics. In total, the expansion contains more than 60 new missions. Players can also create their own guild emblems, that can be upgraded and grant the guild special abilities.
