[Stone Fortress, West side of the southern territory]
The moment an explosion rung out somewhere in the stone fortress, Both Tetra and Einar then looked out of their window, only to see their whole tactical area being overrun by enemy forces. Due to the fact that this came into a sudden attack, a lot of the southern warriors were caught off guard as they fought bitterly with the invading force from the western tribal warriors.
But before the southern forces were even able to react to defend themselves, the whole open area and inner places in the fortress were immediately filled with the western force warriors. Even the walls could be seen being slowly overtaken by western forces, despite the aggravated roars from the defending units.
