Dark Age of Camelot is set right after the death of King Arthur. There are three realms that players can choose for their home. Albion is the land of Arthur with Camelot as its capital city. Midgard is based upon the Nordic myths. Hibernia is steeped deeply in Irish Celtic lore.
Catacombs is a retail expansion pack for Dark Age of Camelot in which players are given the opportunity to explore underground cities - with attached adventuring areas - based on the backstory of one underground player race per Realm. The expansion features a major art upgrade to player character models that provides more detailed facial features, hairstyles, skin tones as well as enhanced armor and clothing options. The expansion also introduces one new player class per realm.
