Originally, Reign was planning on causing chaos inside of the stronghold while the others stayed back and made sure they weren't noticed so that the leader of the stronghold wouldn't notice just how many Tier V beings were present and flee from the stronghold.
Reign believed that it would take him a couple of minutes of slaughtering the Tier IV beings before the leader would appear.
After all, a new Tier V human appearing and attacking a demon stronghold right away was not something that happened every day. Reign was certain that the demon would notice something was amiss and stay back for a bit to try and figure out just what was happening, but to Reign's great surprise, the leader did no such thing.
The leader of the Ethereon demons arrived immediately, which saved Reign a lot of time and trouble, allowing the others to attack right away as Reign dealt with the leader.
Boom!
