Yes, good point. Required a little bit of editing to his backstory - how's this below?
Background:
Arthur is Queen Melina’s brother. Twenty years earlier, she tried to kill him by having the castle walls come tumbling in, and then she stole his Crown. He escaped, with complete amnesia about his previous life, and built a quiet and anonymous life for himself as a stonemason. Leaving all magic aside, he shared a simple abode in the countryside with his family, including his wife Joan and several children.
At the age of 42, his memory, in pieces, began to return to him. He is then called to his destiny by the Alphabet Society to help save existence by prevailing over the sister who wronged him so cruelly all those years ago. Reluctantly, Arthur answers the call to play the Royal violin in this service. He does not want to leave his family, but secretly wants revenge against Melina. He fights these worst impulses in himself.
