I was more talking about the thing that, only alicorns reign about an empire or country so far, but well i still think i missed something at this episode about his story.
The way it was described in the episode, it sounds like Sombra wasn't actually meant to be in charge; but instead he came in and took over.
Presumably, it was Cadence's family line was ruled the Crystal Empire before Sombra invaded.
and then eventually going insane and took over the crystal empire as his alter ego King Sombra the end....or is it?
