The magical faerie sword wielded by Arthur, the High King of Albion (or Britan as it was later known) during his reign. Replaced the sword drawn from a stone (which proved his parentage) for differing reasons - some tales say the sword shattered, others that Merlin simply thought he needed a new one. Its scabbard was said to heal any wound, its blade to carve through any foe.

Middle English, Excalibur.
