As for why- there was a psychic duelist who was possessed by an artifact, recently. Unfortunately, they don't remember the attack, and by the time we got there, the artifact was shattered and had no trace of energy left on it. We've got no leads on what that could be - other than there's a good chance it might be related to this mess with the resurgence of the Numbers, the Number Hunters, and the Immaterial Demons.
The only way we'd be able to recreate the event is if we had someone who was able to tap into the psychic link shared by the duelist and whatever possessed him at the time.
