It had been six months since the forgotten events of the Overlord. Half of that time Princess Luna had been locked away in her quarters after a horrifying revelation.
The great deity, Guardian, had lost his memory of Equestria to The Overlord, also taking all the time Guardian spent raising the royal sisters in the midst of a bloody war. The sisters were devastated, they owed their lives to him for all the wars fought against stronger foes. He had always been there to save the young Equestria time and time again. There is no pain greater than being forgotten by someone you love.

It was month three. Luna was still hidden away and Celestia was going through a stack of documents, stamping one after another. She always tried to bury herself in her tedious royal duties. Celestia kept a steady pace, stamping one after another. This was one of the things Guardian taught them to do, how to keep from going mad by stamping one after another. Thoughts of her mentor crept into her mind. Celestia's pace quickened, stamping one after another. Everything she stood for was created by Him, and now she tried to hide her grief, stamping one after another. Anger was overcoming the princess, these tasks were utterly pointless. She was going at a furious speed now. Tears were forming at her eyes and she uttered small sobs. Why them, why here, how could the only other family besides Luna not remember her? Celestia threw the stack of papers across the room with a furious scream. She collapsed on the floor sobbing uncontrollably. She was just another life to Him, not meaning anything special. She was small and insignificant to his great power.
When she heard footsteps behind her, she whirled around ready to blast the intruder out of blind rage. She stopped herself when she saw the two-legged metal being approaching her. Guardian had a sorrowful look, he was moving cautiously, as if he feared the white alicorn in front if him might not be real. He stopped a few feet away from her and gently placed a robotic hand on her cheek. Celestia leaned into his hand. Closing her eyes she cherished the gesture, despite being mostly metal, Guardian gave off this warm and comforting aura. A sensation she hadn't felt in centuries. When she opened her eyes Guardians expression changed to one of a loving father. Hope flared in Celestia. The impossible chance of His complete return seemed to be happening right in front of her.

His next words gave Celestia the strength to fly to the moon and back,

"I remember."

Author's Notes:

Nothing like some feels to start this off.

For those who so desperately wish it to be so, no this is not actually romance. Guardian's love for Celestia and Luna is that of an adopted father, I've tried to make that very clear. If you haven't read the first book please do so now, it'll make a lot more sense. I hope you enjoy this next installment.
