Sharky and Thomas were ready to tour over Asgard.
But their sightseeing stopped, when an alarm was announced.
Several stealth aircraft appeared in the sky, one after another.
"How did Asgard not capture them," Heimdall was confused.
He only managed to destroy one of them, but the rest eluded him.
Asgard's anti-air unit was deployed to combat the invaders, but they proved to be highly agile, easily outmaneuvering Asgard's defenses. The enemy even destroyed all of Asgard's anti-air turrets.
Heimdall, realizing the enemy had breached Asgard's defenses, activated the palace's energy shield, believing it would protect the royal family.
To everyone's shock, the shield was shattered, the first time it had ever failed to work. This meant that the enemy had infiltrated the palace, as the shield could only be destroyed if the energy core inside the palace was damaged.
These attackers were the army of Shadowforge. After passing the Heimdall, they arrived in the Asgardian atmosphere.
