I've lived all my life knowing Princess Celestia was the one who raised the sun and Luna raised the moon. I learned they had massive power, more than any unicorn alive, more than every unicorn combined. They are said to be immortal, but are they really? I have many questions and I want answers. They may be able to raise the sun and moon, but how did the sun and moon get there in the first place? If they can move mountain, why can't they just make them disappear out of thin air or drive it further into the ground? I found out they have limited power. Now, about their immortality. Are they really meant to live forever? It just seems highly improbable. Ever heard of the phrase, "Every pony and everything must eventually die?"
