The rebels had the fool hope to definitely stop the armies of Evil. Unfortunately, it seems they underestimated the capability of Orcs and Undead to fight back in the Foothills… and they failed in their rebellion trial.
It was a bloody struggle and only a few rebellion leaders could survive and retreat in time. They finally reached a safer place in the Fourhills. They will only have a few hours to prepare their defense as the enemy could rise at any time.
The Evil armies have received the order to show no mercy: there will be no prisoner.
