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 nephew, 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 supported the cause of Old Narnia. After the Second Battle of Beruna, it is unknown what happened to the Prunaprismia or their nameless child (Caspian X's cousin), but it is likely that she and her infant son left with the other Telmarines who didn't want to stay in Narnia under the control of the Old Narnians.

Appearance
She was known to have red hair.

Film Portrayals
In the Prince Caspian film, she is played by actress Alicia Borrachero. In the film, she has black hair rather then the red hair mentioned in the book, and she also wields a crossbow during the raid on Miraz's castle that was added to the movie. She expressed shock and horror when Miraz was forced to admit to the murder of his brother, of which she was apparently not aware. She is portrayed as more sympathetic as even though she loves Miraz, she is horrified by his act of fratricide and doesn't seem as hateful towards Caspian. Later, she, her father, Lord Scythley, and Glozelle (along with her infant son) are the first to accept Aslan's offer to return to the world of their ancestors.

In the BBC Series, she is depicted very closley to her description in the book. She has red hair, is shown to be visibly pregnant, and her dislike for Caspian is established by her open hostility towards him, calling him an ungrateful little wretch, and telling him to be silent in a harsh tone when he calmly expresses the desire for more independence.
