Merlin.<br/>Usual appearance.<br/>(http://i317.photobucket.com/albums/mm391/MasterMerlyn/merlin-rick-wakeman.jpg)<br/>Image by Rick Wakeman<br/><br/>A very knowledgeable and powerful wizard.  He was involved in the conception of Camelot, and Arthur.  There are many different beliefs around the wizard, but it is commonly known that he can for-see the future to at least a limited ability.  As for the lesser known abilities, he can communicate with animals, as well as change his appearance (shapeshift).<br/><br/>He is Arthur's teacher, adviser, mentor, and friend.  Many believe that Camelot was the idea of Merlin, and he simply pushed Arthur to make it a reality.  And others believe that he simply tries to uphold honest virtues, and that instilling them in Arthur made Camelot.
