PLEASE READ: This is an old story. Since then, my writing abilities have improved. Please try to ignore any old grammar or spelling mistakes. This story is in the process of being re-written. Chapters may be shorter or longer with info added or removed, so if things don't make sense, bare with me.
I recommend you read only the updated chapters for now. Check back later for updates.
If a chapter has "Old" next to it, it's still in it's original version. Bare with anything that doesn't make sense or anything silly.
If the chapter has nothing next to the title, then it's an updated chapter.
If the chapter has "New" next to it, then it's an entirely new piece of content.
