(To be labeled for the most part as it goes along, more than likely wrongfully only due to incompetence. Anything wrong with the tagging, grammar, spelling, character personalities, etcetera, etcetera, please feel free to point out in a mean bellowing tone and it shall be corrected if is it truly wrong, for the betterment of all who dare to read this. Thank you.)
