The two men fell through the starry sky, with Eragon holding the emperor's arms. As for the amplification the emperor had before, it was no longer useable against the Sin of Wrath, Ageless Breaker. Thus, he was helpless once caught by Eragon.
"Unhand me at once!" roared the emperor as he struggled to break free. However, since his absorptive powers have been disabled, Arthur could use his runes again. Thus, golden mana exploded to counterattack the emperor's strength, although the difference was still significant.
"Feel… my… wrath…" said Eragon in a hoarse voice before pulling the emperor toward himself and kicking him with both feet in the gut. His stomach caved in before the emperor coughed up blood and was sent flying downward.
