Ragnarok is nigh, and the realms of the great tree Yggdrasil are in grave peril. Fear spreads like a disease through the nine realms and with it, rumour of a new hope. There is one who inspires the beings of the wholesome realms to rise up and fight, but he has no training and as a demigod cannot possess the power to defeat their enemies; or can he? Jim, the demigod son of Thor has secrets locked away in his blood to which even he is blind. The power growing within him has not yet fully developed and when it does he holds the power to save Yggdrasil and all who dwell upon her braches. But does he have the skill to use it? Can this untrained demigod truly save the nine realms, or will all perish in fire, ice and darkness?
