Doctor of the Seas I: Infectivity

This young stallion is named "Anonylyth", his parents passed away. Anonylyth flies across the seas by himself, until finding what he was looking for: Ye Olden Home of Twilight.

Yes! I found it! Now I can learn the true history of 'Twilight Sparkle the Mysterium'!

It is no ordinary home, as it is a sunken vessel with a faint silhouette as the only indication of where it is. It is 9,001 miles down below the surface, which would take so long to get down to that none know how to last under without drowning or collapsing. Except...

"Immortalitatem!"

He knows the Immortal Curse, a curse that grants complete immortality for a time ranging from one minute to ten years. The only source in which anyone can learn it belonged to Twilight Sparkle the Mysterium, who was also the only one ever to know how to cast it. The only downside is that when it ends, it has a chance of instantly killing the user that bases on nine times the amount of years it on. Anonylyth's intentions are to use it for the ten-year length and spread the history of Twilight Sparkle the Mysterium to the rest of the world, even if it means suicide.

Anonylyth swims all the way down to the sunken vessel while under the Immortal Curse, taking a month of his time away. He's surprised to find it in only two pieces when he does get down there, there's even an air pocket down there. And there they are the journals of Dr. Sparkle, all perfectly set up on a bookshelf. Also, Twilight's skeleton is down there. Even in death, she still dons that brown robe and elegant cape of lavender. She even still has her signature "Purazumaken", a Katana that has a button on it that activates a blue line of plasma running across one side of the blade. Anonylyth picks it up and pressed the button, and it surprisingly still flawlessly worked.

Anonylyth notices a quill resting on the page of an unfinished journal, "I remember it clearly, I discovered just how long the Immortal Curse can last for ten years ago. But if my calculations are correct, then there should be a 90% chance that this will be the day tha-- aaaaagh...". That was all it said, she clearly died while writing. And she groaned as she did.

Uhhh... if she was dying while trying to write this, then why is the groan written down? I mean, she wouldn't write it, she'd say it! Ugh! Whatever."

Nonetheless, Anonylyth looks through the journals and finds that they're all numbered 1-20. He started reading the first one: "Doctor of the Seas I: Infectivity".
