Twilight Sparkle: “What…what ARE you?”

Alphamega: “I am what I was when the world was born. I am what I will be when the world dies. I am what you were as a child, what the pegasus was as a child, what the pony was as a child. I am what you shall be when you are as bones in the earth. I am who I have always been, and never been, and was and is. I Am. I Am Not. I Am All. I Am Nothing. I am the Root and Leaf, the Light and Dark, the Body and Soul. What is, was, and ever shall be.”

Twilight: “…Good for you.”
