Strangely, nopony started to speculate about this series until the Mane Six started showing up.
Dark Feather is Rainbow Dash
- We've seen her cutie mark on Dark Feather's flank.
- Jossed: She has one of Rainbow's cutie marks, but isn't Rainbow.
Dark Feather is Flurry Heart
- If Flurry Heart is Lace's mother, and Lace and Skywalker are still sisters, and Dark Feather is Skywalker's mother, then Dark Feather is Flurry Heart.
- Given that Shining Armor acts as if Flurry Heart is dead, and Flutterbat wiped out nearly all the alicorns, it's possible that Flurry Heart was one of her victims and turned to the Nightmare Force to get her magic back.
- Jossed: Flurry Heart is Padme.
Dark Feather is Sweetie Belle
Dark Feather is Scootaloo
Dark Feather is Luna
- Jossed: Luna is Yoda.
Dark Feather is Starlight Glimmer
- It would fit with Starlight being Twilight's student, as Anakin was Obi-wan's.
- Jossed
Dark Feather is Maud Pie
- The helmet looks like Maud's hair.
- Jossed
Dark Feather is Sunset Shimmer
- Jossed: The author has mentioned saving Sunset Shimmer for something else.
The Empress is Bon-Bon
- Because she is a angry little mare and is still pissed about the odd voices and hiding under a different name and the incident with the apples and Applebloom? Dark Side anger there. Lyra probably died and she went full on Sith.
- Jossed
The Empress is Luna
- They did name the battle station the 'Nightmare Moon,' after all.
- Jossed: Luna is Yoda.
The Empress is Pinkie Pie
- Only one pony can see into the future.
- Confirmed

- Probably Scootaloo, because reasons.
- Jossed
The Empress is Surprise
- It would be Surprising.
- Jossed
The Empress is a Pinkie Clone.
- Jossed It's The real Pnkie
