A wedding gift from King Serberon to his future Queen, the Angel of 'El Horidore is an ancient whistle used for calling dragons. With one single blast, the whistle will call all of the dragons in the world together. The Shape want to find the whistle and use it to kill the dragons, steal their draconite, rebuild the Stone Cross and obtain the powers of immortality and invincibility. Sir Ragnarok cannot let this happen. He is sure the Angel of 'El Horidore is hidden near Dragamas and sets a task for his students to find it so he can protect it from the Shape. Sammy Rambles and his friends Dixie Deane and Darius Murphy embark on their most serious quest so far.
