Pulling his collar over his nose in case it was some sort of poisonous fog, Ren rushed down the corridor to flee the grasps of the malicious clouds. Humming filled his ears, occupying the mist, forcing him to pick up the pace as his instincts screamed at him.
Accompanying the constant humming came a roaring thud reminiscent of a stomp. First, this clomp came from his left, then his right, behind him, and all around him it continued. There was barely a recognizable moment that his feet came into contact with the ground as he ran with the utmost speed he could muster, turning down corridor after corridor without any regard for his direction.
Every hair on his body stood up, everything in his body yelling at him one thing--"Protect your back". Ren quickly turned around just in time to witness one of the walls crumble, or rather blast away as if met with the force of an explosive force.
