Upon looking at the enemy's den, they saw a mountain that has a hole on its side. Guards were present at the entrance and others were getting in and out of it. They were resting for a while as he waited for the right time to attack. Others just waiting for his signal to attack their lair. Ranger and Rogue knew some parts of the outside of the den as he was the one who led the scouting mission. Also wreaking havoc ahead of time made their overall strength lessen.
The others then were rounded up by Original. Signalling that they will attack soon. Confirming that the place was their den, they started their raid.
