The Hall of Heroes is a museum all about warriors throughout history. It’s full of swords, bows and arrows, helmets, boats, armour, shields, spears, axes and just about anything else that a warrior might need. But this isn’t just another museum full of old stuff in glass cases – it’s also haunted by the ghosts of the warriors whose belongings are there. Our great grandfather, Professor Blade, set up the museum and when he died he started haunting the place too. He felt guilty about the trapped ghost warriors and vowed he would not rest in peace until all the other ghosts were laid to rest first. And that’s where Arthur and I come in…

On the night of the Professor’s funeral Arthur and I broke into the museum – we knew it was wrong but we just couldn’t help ourselves. And that’s when we discovered something very weird. When we are touched by one of the ghost warriors we get transported to the time and place where the ghost lived and died. And we can’t get back until we’ve fixed whatever it is that keeps the ghost from resting in peace. So we go from one mission to the next, recovering lost swords, avenging deaths, saving loved ones or doing whatever else the ghost warrior needs us to do.

Fortunately while the Professor was alive I wrote down everything he ever told us about these warriors in a book I call Warrior Heroes – so luckily we do have some idea of what we’re getting into each time – even if Arthur does still call me ‘Finn the geek’. But we need more than a book to survive each adventure because wherever we go we’re surrounded by war and battle and the fiercest fighters who ever lived, as you’re about to find out!
