Annihilation: Silver Surfer

Tenebrous and Aegis, two very old and powerful beings, were freed when the Kyln was destroyed. Galactus summons the Silver Surfer, former Herald, to rejoin the fold and stand against these two. He agrees, on the condition that he retains his conscience and remorse this time, and Galactus does so. The Surfer is restored to full power just in time to repel an attack by the Seekers of Annihilus, who do not stand even the slightest chance against power of this magnitude.
