Know is current captain of the crew Imperial Eagle Armada and current monarch of the flag Eagleia on the Hunter Ocean. Know first came to Puzzle Pirates in February 2008, landing on Alkaid Island on the Hunter Ocean, but soon moved to Aimuari Island. He spent a long time on Hunter. When a new ocean, Malachite came out, he decided to move there, but changed his mind and went back to Hunter soon afterwards.
He went dormant for some time in the middle of 2009, but soon returned and is now playing again. He only really plays on Hunter, but he may be found sometimes on the other oceans going by the same name, or by the name Knowledge on Cobalt and Viridian.
