Pendragon is a political activist in the United Kingdom who was seeking the dissolution of the Lord Protector's Office. His true identity is unknown, but he is said to be the resurrected King Arthur of Arthurian legend said to have returned to help England in its greatest time of need. He made a number of famous speeches and united left leaning political groups. He'd advocated for returning the government to the people.
The first sighting of Pendragon was in December of 2062 during the Midwinter Festival in London’s Hyde Park during an anti-government rally. Pendragon was said to look like a plain man in a turtleneck and trousers. He took to the stage and pulled out Excalibur before giving his speech.
Several theories of Pendragon's true identity have been discussed, however most agree that it's relatively inconsequential.
It is believed with his ability to avoid assassination and capture, that he may be magical in nature. This could imply that he's a free spirit or possibly a dragon (some suspect Rhonabwy). There is also a bounty on his identity by Ordo Maximus, which could mean he's a vampire. He could be the real King Arthur that made a spirit pact to gain immortality as well.
