Undead
The battle stopped on all fronts, the emperor just defended the whole Palace with the defensive formation and blocked all the invasions at the same time.
But four hours is a lot a time and he was not sure whether he would be able to stop all their attacks for the next four hours.
He started slaughtering the minions who are in the front, to try and instill some fear into the people at the rear, but it turned out to be a futile action and the waves of people never stopped.
After more than half-an-hour, there was a first nick on the formation.
At that moment, a saber ray flew out from the emperor and hit the priest right in the chest.
The formation seemed to have an attack function too and its attacks are even amplified. The laceration on the chest of the priest is a clear show of might.
The priest raised his hand and stopped the advance of all the followers.
