Linda ordered the siege weapon operators to aim below the openings where the defenders were. The stones from the catapults and trebuchets broke the mountain wall. The defenders lost their footing when the ground below them crumbled. Both the soldiers and the mana cannons fell and tumbled down the mountain under rains of stones.
Boron's force also charged after the mountain lost its protection. Balgadur had several entry points. Boron was in charge of entering from one of the side entrances.
After dispelling the protective rune diagrams, Master took out one of his guild's siege weapons, the dragon-head battering ram. This ram immediately took action as it bashed its metallic dragon head upon the main gate. The soldiers who followed him rushed forward and attacked the gate to increase the pace. The armored ballista was left behind, it had served its purpose.
Without the protection from the rune diagrams, it didn't take long for the main gate to shatter.
