Sirius executed Realm Ender and destroyed every enemy around him and even dealt damage to the Horseman of Death and Horseman of Pestilence. Sirius was about to deal greater damage to both the horsemen, but a barrier suddenly got erected that blocked most of the skill damage from Realm Ender.
The Realm Ender skill managed to delete 10% of the two horsemen's health and it would have been more if the Dragon of Revelation did not protect them. When Realm Ender ended, Sirius immediately became smaller and also became weakened but the fear that he ingrained on the two horsemen have taken root.
Even the Dragon of Revelation feared the Abyssal Fenrir because of his might which is why all three looked at Sirius with burning vengeance. The Horseman of Death became covered with dark smoke as he charged towards Sirius. The Horseman of Pestilence released three arrows that rooted Sirius into place. The Dragon of Revelation collected energy into its mouth as it locked onto Sirius.
