Personal log of Star Swirl the Bearded, entry # 913074

I cannot believe it has come to this. I had hoped I would have more time... huh... time.
I'm the right pony to be talking about it. I had been postponing my own end for so long I can hardly even remember when it begun.
For so long I had been stuck with my nose between the books, researching the magic, I had hoped to reach some level enlightenment, my entire life was meant to be studying magic, my purpose, my... destiny.
My greatest shock was when my own apprentice, Clover the Clever, ended up defeating Windigos, the storms of Hate, and establishing the knowledge that positive emotions are necessary for Harmony and Order to exist in both ways of life and magic.
I was too stubborn, too... proud at that time to admit it. 

"How could have magic be affected by emotions?! Preposterous! ” I always scoffed, "What does that little filly know? I have already lived her entire lifetime once."

But I learned that the hard way... how terribly wrong I was...
My three greatest failures in life... 
I was unable to protect my students....
I was unable to avert my king's terrible fate...
And now... this... this one last... final spell, which could undo all of my past mistakes and give me some measure of peace...  not just me, but also the twin princesses...
I cannot complete it... I just lack resources... no... I lack friends, who could help me...
I cannot continue on like this. My time is almost up and my own Doubt is now beginning to eat at me, manifesting into something the likes I haven't seen since... Turmoil...
All I can do now is to use THAT spell and put my plan into action.
Celestia... Luna... They have grown into two fine mares, despite King Titan's absence. I can trust them with leading Equestria without my guidance.
This will be my final entry. And if somepony does find my diary, they better use the knowledge in a way they won't end up dooming themselves.
And before I leave... my cutie mark... each time I look at it, I feel disgusted. I was destined to become the greatest magic wielder of all Equestria... and in the end, in its darkest hour; I failed to live up to it.
No… not this time! 
I will live up to the name I have worked on my whole life. 
Using the knowledge I have gathered and powers I have mastered, I will go back and correct that one fatal mistake, where everything could have changed for the better.
I swear, by all the magic that exists in this world, I will be the savior of Equestria.

I… will fulfill my destiny…
