Albion

Albion was a magical sword. It was forged by the legendary Wayland the Smith. It was originally one of the Seven swords imbued with Power of Light and Darkness, but after the events of Swords of Wayland, Albion was the only one of the Seven Swords that remained.

History
Albion was created as one of the Seven Swords of Wayland. Their creation took place "hundreds of years" before the reign of King John of England. Aware of the danger of the Swords' power, Wayland "scattered" them. Albion came into the possession of Herne the Hunter. Albion bore a runic inscription: "Herne’s Son is my master. I cannot slay him." This implies that Wayland knew of Herne and created Albion specifically for Herne's purposes.

When Herne summoned Robin of Loxley to his cave, he gave Robin Albion as part his giving Robin the role of Herne's Son.
