Based on the image, by Equestria-prevails on Deviantart. Two guards, one Day and one Night, having a drink on their night off.
This more or less came about when I wondered at the backstory of the image, saw several other people doing the same, then decided to make it happen.

"Who is he?

No one really knows. Some say he's an organization composed of thinkers and sages throughout history. Some say he's a rank passed down through generations, dating back to pre-Equestrian times. Some say he's an alien from another world, others maybe a time traveler or a ghost or a magical paradox. Some say he's a hero of great deeds, others say he's an omen of disasters to come. While others say he's just a story. A myth. A legend. A shadow in the corner of my history books.

One thing I know for sure though. I'm going to find him.

...one way or another."
