Excalibur

-----

Excalibur, the legendary holy blade once wielded by the legendary figure, King Arthur, was now of Noah's property after a series of insane turns of events.

It resulted that Arthur's family were the descendants of King Arthur himself, although Arthur could have never guessed that as he did not even have the Pendragon surname…

From the memories of Merlin and the Lady of the Lake, Noah got to learn many things about the old world, alongside the truth about some things, such as the existence of "God".

God, the divine entity that existed within the heavens, was an entity that really existed, and it was the one that created the Lady of the Lake, a divine herald that would give Arthur the legendary sword Excalibur, made by the wishes of all humanity and forged within Earth's core into an indestructible artifact.
