Ben's double life continues at the Royal Institute of Magic. To most, he's a talented apprentice and an exceptional spellshooter, but Ben is also a Guardian, responsible for uniting Elizabeth's Armour, the only artefact powerful enough to overthrow the evil dark elves.
With two pieces of the armour secure, finding the third may be Ben's toughest challenge yet. His only clue is a magical key, a tenuous link to a legend called the Silver Dwarf.
With the dark elves slowly conquering the Unseen Kingdoms, Ben races against time to gather the pieces of armour and unite the Guardians entrusted with them. If that wasn't hard enough, new challenges and old enemies await him at the Institute, and his friendship will be tested like never before.
Ben Greenwood is continuing his apprenticeship at the Royal Institute of Magic, hoping things will be slightly less complicated now that he has advanced to the second grade.
Coupled with the sterner challenges that the second grade brings, there is also the small matter of the impending dark elf invasion, making life at the Institute even busier than usual. Ben is the only one who can stop them, by finding Elizabeth's Armour and its Guardians.
Ben has retrieved one piece of the Armour – the boots – but the rest remain hidden. He has just one clue, which could lead to Elizabeth's Helm: an old black and white photo given to him by the Master of Apprentices.
Ben must split his time between his apprenticeship and searching for the helm, before the dark elves strike and all hell breaks loose.
The Protectors is the third book in the Royal Institute of Magic series.
