After finishing the Story Mode in this game where Kronika required her crown to absorb enough souls to use her hourglass to rewind time, it got me thinking of other characters who have used souls in the past. In particular, I was thinking of Shang Tsung and how he absorbed souls to expands his lifespan. From what I remember, it never was specifically states why exactly absorbing souls would expands a lifespan. But after this game, I have a theory. Absorbing souls has a limited time travel effect for the absorber. Time as a whole continues to progress forward, no events in the past are alter, other characters (other than the person whose soul is being absorb) are not affected. Just inside within the absorber body, their genes goes back in time of sort, to their "younger" state. i.e. Shang Tsung genes doesn't causes gray hair and back to grow black hair like when he was young, and he is not a fragile old man but 19 years old. Anyway just a thought.
