Problems Of Invasion.

Aeternus was talking to his demon dukes. 

"This is a competition. There will be rewards for your efforts. Enough Divinity to help you reach the half-divine rank is up for grabs. I will distribute them according to your contribution to the mission. All you have to do is to take your legions and destroy churches on the plane. The more churches and clergymen you destroy, the more divinity you get."

They become even more perked up. Divinity is very important to demon dukes. It is the only way for them to grow and reach the half-divine rank the same as the demon lord. They don't need the encouragement to destroy, but the competition has turned their hobby into a paying job. There's nothing better than that. That makes two people who have just gotten their dream jobs. Helios and the demons.
