My 10th Regression

After regressing 9 times, Alan finally succeeds in his mission. However, he dies in the process, using a technique that destroys his soul. Unexpectedly, instead of regressing back in time to his younger body, he appears 800 years in the future, in the body of a commoner. Did he truly succeed in his mission, or is the entity responsible for his regression forcing him to save humanity yet again?
