The start of the end

The original incarnation of the strongest mortal soul took out a blade from his own pocket dimension, this was the blade that had accompanied him in his lifetime of battle. This was the very sword that helped him seal away the ORIGIN in an unknown place a place that not even the ORIGIN knows which means that the ORIGIN didn't create it. The one who created this miniature universe was none other than the Strongest Mortal Soul.

This miniature universe has trapped the ORIGIN for an incalculable amount of time, not only was it difficult to escape the place but the original incarnation of the Strongest Mortal Soul was able to to seal most of the ORIGIN's power. 

Unfortunately, not even this prison that could trap almost anybody else could hold the ORIGIN forever. 

'Before the ORIGIN is able to escape the prison I created we need to fight him. This might be the last chance we have before utter destruction.'
