Immortal Thor (2023) #6

A LEGEND FROM THE PAST! The All-Father sought answers to his new troubles in memories of old. And to refresh those memories, he consulted his Skald... ...to tell a tale of when Young Thor and Young Loki journeyed out beyond Asgard - on a quest that would determine the fate of all the Realms. This is the story of the IMMORTAL THOR...and of his first Journey Into Mystery.
