The blast sounded which blew up the building base and it marked the start of the invasion raid of Ghouls against the Vampires. The first wave of fighting ghouls was easily shredded by the Vampires who high on battle adrenaline jumped into the fray. But it was just the start, seeing the happening casualties on both sides the leaders were still keeping their full force in check. The night was still young and they were waiting for the opponent to display the full cards first.
Orion was also observing the start of Battle but no matter how much he wanted to take advantage of it immediately, he can't jump into the fray without reason or all his planning would lead to naught. He had to wait for a perfect chance to make his move or else all would become redundant. But still looking at the perishing force, it pierced his heart knowing the more casualties that will happen now, the more danger it would be to his life later.
