Princess Celestia looked gravely at Twilight Sparkle.
 
“My faithful student. It’s not too late to turn back…”
 
Twilight Sparkle stamped down her hoof, but said nothing, Princess Celestia knew there was no changing her mind.
 
“Well, my pupil, for your second test there is a darkened cave far away in the tallest mountain south of Canterlot. It is there that a forgotten knight awaits you holding the Sun Stone and he will not relinquish it until you have appeased him. He was the most powerful unicorn that ever lived. Things were looking grim in the ancient war that had come to claim his village. He knew he could turn the tide, and he did. He let loose the full strength of his power and completely burned away his foes, but in doing so, he burned away his village as well. His friends, his family, his wife, and his three sons.”
 
Twilight looked down at her hoofs, thinking there were no way she could ever hope to defeat someone that powerful.
 
“But,” Princess Celestia continued, “his shame drove him into the mountain and there his sadness turned him to stone–where he has remained asleep for ten thousand years. Your task is to approach him and show him you can shine as bright as the sun but in doing so bring harm to no one. Show him you have the conviction to hold back for those you love, and he will reward you.”
