In a time of fear and uncertainty, the Avengers make a plan to rebuild Asgard, while Sin enacts a mysterious plan to gather powerful godly weapons.
Prelude: Book of the Skull
In the Egyptian desert, Sin and Baron Zemo seek out Sin's father's ( The Red Skull) hidden journal about his greatest failure. After defeating her father's robot guards, Sin relates the story about her father's greatest failure. Back in 1942, The Red Skull with the aid of Baron Wolfgang Von Strucker had come across a gypsy camp that spoke about a long lost fear god. The Red Skull had these gypsies kill several Atlantean citizen to fashion a book that would help call this fear god to Earth. The ritual is performed by the Thule Priest and a bolt of lightning flashes across the sky, but whatever came down did not end up near Red Skull's location. The Invaders discover the Red Skull's plan and Namor, Bucky and Captain America track the Red Skull and his men to Antarctica. In a rage about the death and mutilation of his people, Namor attacks the Nazis on the ground but is soon attacked by a large blue demon. After a long battle, the demon was forced into the cold water and Bucky used a grenade to blow off its head, killing it. The Red Skull retreats with Baron Strucker, saying the Invaders had not grabbed the true prize and the two return to Germany. However, it is a ruse, a mystic hammer similar to Mjolnir had landed in the Arctic and the Red Skull's men built a fortress around it and after many decades, the hammer remained because no one worthy enough could lift it.
After the tale, Zemo and Sin escape the collapsing base and Sin soon betrays Zemo, destroying his teleporter disc and stealing his ship. Zemo watches saying that he hopes Sin gets what she wants because if she doesn't, she had made a new enemy and he will take care of her. Sin soon gathers her men and heads towards her father's old base to claim the hammer.
Fear itself begins
She kills all of Zemo's men trying to stop her, but when she lifts the hammer... the Serpent,brother of odin awakens and frees himself from his prison claiming that Odin isn't the true father of all, he summons seven more hammers to chose some worthy people to become his heralds:
