After the battle of Camelot, the popularity of both Norgales and Iceni among the masses dropped, as the news of them siding with the invaders broke out.
Their loss in the battle caused the deaths of thousands of knights and fighters and left them with no means to defend themselves from the anger of the people.
The situation was so bad, even nobles and common folk banded together to cause a massive riot, breaking the castles' walls and putting most of the kingdoms' officials to the sword.
Both kingdoms were ground to dust within a matter of weeks.
The fact Arthur managed to win the battle despite the overwhelming forces of evil with the sword of divinity really endeared him among common folk and nobles alike.
When King Arthur came to confront them, he didn't even need to bring any knights. The two crumbled kingdoms opened their gates and immediately announced their surrender.
