It's the classic tales that gave birth to the greatest saga of myth and adventure to ever grace the comic book page! The adventures of Thor! While vacationing along the coast of Norway, Dr. Donald Blake happened upon a secret chamber and inside it found a strange, gnarled cane. Upon striking the cane a shower of lightning rained down and the hobbled doctor found himself transformed into the Mighty Thor, God of Thunder and champion of Asgard! In these pages you'll journey to across the Rainbow Bridge to eternal Asgard, meet Lord Odin, Heimdall, Balder, and Thor's evil half-brother, Loki, for the first time. And to top it off, the mythological origins of Asgard are revealed in the fan-favorite Tales of Asgard backup features.
