Six guilds are competing for the chance to rule Albion and the strongest are about to wipe out the weakest. But then along comes Jed Greenleaf from the Leaf Guild, the weakest of the guilds. 

Jed looks like an ordinary boy, but when he gets angry, his skin covers over with an extraordinary armour made of bark, and he can command the strength of an oak tree. It turns out he has other powers too...

Could he be the hero that the Leaf Guild needs to win at the Punchbowl tournament? It just might be that this year Jed can turn over a new leaf in the history books, and bring glory to his decaying Guild and peace to Albion . . .
