[@Dead Cruiser] All souls possess a mantle. It so happens that the mantles of famous spirits, such as Hercules or Shakespeare, tend to be considered an important part of them, and as such, acquiring a famous spirit's mantle effectively marks you as the new instance of that spirit, even if your personality remains intact and/or the spirit providing the mantle is not dead. A human acquiring a spirit's mantle does not turn into a spirit themselves, nor does a spirit acquiring a human mantle turn back into a human.
