Excalibur

Excalibur formerly known as Uzriel's sword is the legendary sword of King Arthur, sometimes attributed with magical powers or associated with the rightful sovereignty of Great Britain.

Uzriel
The sword was originally the sword of the Higher Angel Uzriel. He used it to train and fight great evil's. However, after Uzriel fell from grace, the sword became destined to find Uzriel in every life after that.

Becoming Excalibur
According to the legends, Excalibur was given to Arthur by the Lady of the Lake sometime after he began to reign. After the death of King Arthur, Sir Bedivere threw Excalibur into the lake. A hand then rose from the water and took it into the lake. Another legend says Excalibur was drawn from a stone by Arthur to prove his royalty.

Wyatt Halliwell
Wyatt Halliwell was revealed to be the new owner of Excalibur no longer after his birth. His mother, Piper Halliwell was chosen as the New Lady of the Lake. She took care of the sword until her son was old enough to wield it.

By 2030, Wyatt is very confortable with his sword once he shows good command wielding it. He destroyed the demon Doom using Excalibur along with Prue Halliwell who was wielding Hadhafang at the same time.
