Thor #4

MEANWHILE, A TALE OF ASGARD... With nine great realms cut off from the tenth, old enemies grew restless - and hungry eyes fell upon Asgard's empty throne. Ulik, Lord of Trolls, was on the march - and which hero would rise to force him back? And which rabbit would rise to aid that hero? This is the story of THE SON OF THOR...and how his great tragedy began.
