Prunaprismia

Queen Prunaprismia was the wife of King Miraz I, the former king of Telmarine-ruled Narnia, the usurper of the throne from King Caspian IX, and the foe of the true Narnian king, Caspian X. Prunaprismia deeply loved her husband, but was a strong opponent of her relatives, including her brother-in-law, his wife and even her brother-in-law's son, her adoptive son Caspian X. Despite the fact she did not like Caspian, she allowed her husband Miraz to adopt him.

Miraz and Prunapismia however were selfish, and when Prunaprismia had a son, it became clear that because they now had a direct heir, and the troublesome Caspian would have  to be executed. Doctor Cornelius helped Caspian X escape the castle and he raised an army of people who suported the cause of Old Narnia.
