The powerful forces of the world have gathered as the battle to defeat the Dragon of Revelation is unfolding. The Daemos Elders sealed up the space so that the remaining three of the Horsemen of the Apocalypse do not escape. It is also created to deter those that want to disturb the battle as it also bards those that want to get inside.
The Dragon of Revelation knew that it is currently trapped inside this space as long as the three Daemos Elders are still alive. The remaining three of the Horsemen of the Apocalypse are not necessarily its ally just because it was released from the seal. The Dragon of Revelation knows that the three horsemen are just using it for their own gain.
