The moving pieces

In a universe different from Ren's own universe in a dimension hidden from what can be observed a grand battle was taking place. One of the Old Gods was fighting a group of mortals in his own dimension. 

The Old God was in his true form and was the size of a planet while the opponents he was facing were smaller than ants in his view. Yet these small insignificant beings had wounded him so. At the moment the Old God had the advantage but his body was already filled with numerous bruises, cuts, and burns. He an almighty being that could wipe out planets with a swing of his hand was having difficulty fighting a bunch of mortals. 

On the other hand, the mortals he was facing were now on the ground some coughing out blood, others were bleeding badly, and the remaining ones still standing were trying to heal all the injured.
