This group is for anyone that has the fan theory that Sunset Shimmer and Sunburst are brother and sister.
This group also welcomes SunsetXSonata shipping. There must be at least one story of them returning to Equestria to meet Sunset's brother and or extended family. And any story that portrays Celestia as being in the picture is welcome.

It may never be shown on the Show, But the theory will live on here . Any stories that revolve around them and the mane six, or them and Starlight Glimmer are welcome.
And keep the comments section civil or we will unleash the hell that is the Ban hammer on you XD.
