Payback's a witch 20

Witch sisters Agnes and Hedvig are doing a spell when they are jumped by a knight and his page. They both try to use magic to defend themselves, but before she has time to do so, the knight slashes Agnes across the chest. She falls back and he runs his sword through her. Meanwhile, Hedvig shoves the page away and uses her magic to end him. She then turns her attention towards the knight, as they both see what the other has done. He tries to cut her down, but her rage is stronger and she kills him with a single spell. She then goes to her sister and, finding that her sister is dead, she tries to heal her. When she finds that she can't, she dies by her sister's side. (Either from grief or magical suicide, not sure about that bit.)
