Day 356, Year 998

Only two more years until I can see my sister again. How I long to see her face again! I want to throw myself at her, begging for forgiveness. But how could she forgive me? I've done nothing but hurt her.
She'll never forgive a silly filly such as myself. I'm a traitor. A bad pony! And I'm a pony who betrayed her own sister, a foal who never once accepted comfort from others who loved me. And I'm also ashamed of myself.

This is what Luna writes in her weakened state, fighting for control over her more powerful parasite. She hopes that once she's released from her prison on the moon, she can break away from her prison as Nightmare Moon.
