Master's Defender

Unreleased Eraqus's Keyblade is a Keyblade used by Master Eraqus in the upcoming game Kingdom Hearts Birth By Sleep. It has a dark gray shaft that tapers outwards at the ends and has a boxy guard, made up of small light gray boxes and copper rods. The teeth are in the shape of an "E", the first letter in his name. His keychain has the same symbol that appears on his, Ventus's, Terra's and Aqua's clothing. In the final episode of Kingdom Hearts Birth by Sleep, Ventus and Aqua return to the start of their journey, the Land of Departure, the world now shrouded in darkness. There they find Master Eraqus's Keyblade, the weapon left behind in same place since Erauqs's death at Terra's hand. Aqua uses the keyblade to create the Chamber of Waking, and brought the blade with her upon departure.

At the end of Aqua's scenario, we see her in the Realm of Darkness. Just as several Darkside Heartless prepare to attack, she summons this Keyblade rather than her own.
