The construction of the new city of Asgardia reveals a cave, sealed long ago by Odin. When Thor smashes this tomb open, he frees the Mares - a race thought mythical even by the gods - to prey on his dreams and those of all in Asgardia and Broxton. Elsewhere, the Enchantress takes advantage of Dr. Don Blake's desire to be a god to unleash the dread new companion she calls her Keep. With only a bookish elf and a tormented Goth teen for allies, the Odinson must face his fear in a dream from which he cannot wake. Collecting: The Mighty Thor (2011) 12.1, 13-17
