Master's Defender

Eraqus's Keyblade is a Keyblade used by Master Eraqus in the game Kingdom Hearts Birth by Sleep.

Design
Master Eraqus's Keyblade has a smooth, cylindrical, grey shaft that tapers outward at both ends. It has a boxy guard, made up of two small, light gray boxes and copper rods. The base of the guard connects to the handle, and both sport several small indentations lining them. The teeth are in the shape of an "E". His Keychain is made of of several simple chain links and its token has the same symbol that appears on his, Ventus's, Terra's and Aqua's clothing.

Story
After defeating Vanitas at the Keyblade Graveyard, Aqua returns with a comatose Ventus to the Land of Departure, which is now shrouded in darkness. There they find Master Eraqus's Keyblade, left behind where Eraqus was destroyed by Xehanort. Aqua uses the Keyblade to create the Chamber of Waking, and takes the blade with her upon departure. Perhaps due to her unfamiliarity with the weapon, Aqua chooses not to use it in combat against Xehanort.

After being trapped in the Realm of Darkness and losing her own Keyblade to save Terra's body, Aqua is shown wielding this Keyblade as she wanders the dark land.
