User blog comment:It's Good to be the Queen/Gwen's Revenge - a Pendragon heir/@comment-4892425-20121112123602

Here's a better plot twist: what if Uther had a failsafe in place to protect Arthur's rights to the throne? What if Uther drew up his will that shows he admits Morgana is his daughter - but he does not name her heir to the throne? He explains the circumstances of Morgana's conception and birth, and citing Camelot's inheritance and succession laws, legally declares her illegitimate issue; therefore ineligible for the throne. It also hampers her on the marriage market. Nobles would look down on her as a royal by blow; and having children with her would be useless because those children would not be regarded as legal heirs because of Mom. Morgana has been screaming all this time she is the rightful heir, and she'll see under the law she's not. It won't stop her from trying to take the throne, but it will be one hell of a kick in the gut.
