Untold Legends: Brotherhood of the Blade is a launch title for the Sony PSP handheld video game system, developed by Sony Online Entertainment. It is a third person action role-playing game in which the player can complete various quests for money and items. Untold Legends can be played cooperatively with up to four other players via Ad Hoc.

The player can choose to be one of four characters (Knight, Druid, Berserker or Alchemist). The goal is to save Aven, a city so high in the mountains that it often appears to be floating in the clouds, from the attack of various creatures. This "floating city" is the last defense of humanity against a sudden onslaught of dark, foul creatures. It is up to the player to explore the world of Untaca and its various regions, searching for items, talking to people, and killing monsters.
