Book IV
Dusk used to think he was the most unimportant, useless pony that had ever lived. He didn't think that anypony would accept him and he would always be alone, save for one. How wrong he was. With the lord of chaos sealed away once again and his true destiny discovered, to say Dusk has come a long way from where he began would be an understatement.
Now he's the Seventh Element, new responsibilities as well as new opportunities have been opened up to him. An education, under one of the most powerful beings in Equestria has begun, allowing him to expand upon his magic, if he can handle it. At long last, he has taken his his friendship with Twilight to the next level, but that was only the first step. Now, they both must learn not only the magic of friendship, but of romance too.
But not everything is as perfect as it appears. Blackhole Doom may be gone, but his deeds and memories remain in Dusk's mind. Can he cope with the scars his darker self has left? Will he and his friends be able to confront them or will he keep them locked away? A story is told of a Fallen Soul, a fallen hero from time long past. But how much of it is actually a story and could it be something more?
With all of this, meeting new ponies, the good and the bad, new lessons to learn and new adventures to be had, it is true to say that Dusk... has finally dawned.

Book II
Brought out of the darkness of solitude and into the light of friendship, Dusk returns once more to see and learn just what magic and wonder friendship has in store for him. Once thinking he was the most useless, pointless pony to ever exist, he has now found those who care for him and appreciate him for who he is, opening up new possibilities never even considered.
He will join the girls on their adventures and experiences with friendship’s magic, helping them along as they go, having a few of his own and learning and discovering new aspects of himself that become open now friendship is known to him. Along the way, he will also make new friends, challenge his own beliefs and convictions once more and just discover how much more wonderful life is with friends as a part of it.
But that’s not all that concerns him here. He needs to do something different about himself, but what? He has his colour magic, but where exactly did it come from and are there others he shares it with? Twilight may be his best friend but… what’s this new feeling that he has when he’s around her now?
All of this will be explored, as Equestria prepares to see a brand new Dusk.

20-year-old Ryan Burbank is living with his girlfriend in their woodland home when he is struck by a mysterious infection seemingly out of nowhere. To everyone's horror, his sickness spreads quickly throughout his body, shutting him down one piece at a time. The doctors are at a loss of what to do about this new form of bacteria. Ryan and his loved ones choose to keep fighting until either a cure can be discovered...or the pain becomes too much.
At the height of his suffering, he discovers a happy little show while watching television in his hospital room. The bright colors and happy attitudes of the cartoon equines provide him with a much-needed escape from the daily pain of being killed from the inside.
Eventually, the pain becomes too much and he decides it would be better to go out surrounded by his family, in the embrace of those who kept him company throughout his short life. Just as he starts to fade, his eyes wander to the screen of the hospital room television and the cartoon ponies who adorn it. Something strange begins to occur...almost like the screen is pulling him in. Tunnel vision, maybe?
No, that can't be it...why can he hear his name being called by a very familiar voice? And why is she...crying? Who is this crying, familiar voice and why does she seem to know him?
