Raising the Moon

Luna, racked with grief, helps her sister to raise the moon every night while locked away on the inside. She had no idea why she did what she did, and plans to apologise to her sister.

Why did I do this? What happened to me? Why am I here?

Those were the only things Luna could think of, locked away inside the moon. She had one thousand years to do so. But why did she do it? She wasn't even jealous of her sister, not in any way, not until she turned into a monster.
