The Angels on the ship saw what Mark had done with the Nightmare Sharks and many of them realized that there was no way for them to go back. The angels obviously weren't comfortable with this, but the lead ship docked at the port, and they saw their king coming down from the ship calmly. So, the rest of the angels had to rush and follow along so they wouldn't leave their king at the mercy of the demons.
As King Richard got to where the demons were gathered, he stopped as he faced off against Hunn. The two races just stood there and watched one another.
There was something primal about the way their muscles twisted and they bared their teeth at each other. Almost like they were itching to start a fight right there. But before things could get too bad, Hunn greeted them and immediately told them what Mark had just said.
"Anyone that attacks a member of the opposing race will have ten members of his own race killed."
