Gauis ~ "I put my life in your hands every day, Merlin, as do Arthur and Gwen and all of Camelot, though they may not know it. You're the one who holds the fate of this kingdom in the balance".

Gauis is Camelot's court physician and Merlin's guardian and mentor. Once a magician himself, Gaius has long since abandoned the practice but even so is willing to help foster Merlin's talents, and comes to love him as his own son. An eminently wise man with a long memory, Gaius is one of Uther's closest advisers, and always among the first to realise what is really happening when magic threatens the kingdom. He supports Uther even though he disagrees with him often helping Merlin save the lives of those wrongly accused. He holds on to the hope that Arthur will rule differently and magic will once again be accepted and Merlin will get the recognition he deserves.
