The brave Knight Lights (Sir Stilton of Thorn, Lady Lionpenny, Sir Ironheart and Magnabumble) share an adventure in which Magnabumble attempts to thwart an intruder who turns out to be the tooth fairy. The motley band of Knights must save silly old Magnabumble and protect the family house in the process. Volume One of the Knight Lights also tells the story of how the Knight Lights came to be protectors in the night with their everlasting lights. The funny and talented crew patrol by the light of a sword or shield, standing watch over all who sleep within their glow.
