If Arthur is coming of age and since Camelot is in Wales, he would be 17 and turning 18, because that's the day you become an adult, so that must mean the Merlin is 16/17 and Morgana would be 20, because she's too young to know about the war and Gwen is older than Morgana but also is too young to know about the war so she's probably around 21/22
