Now that Twilight's a princess there are going to be challenges ahead for her and maybe an old enemy will return that puts everyone in danger. More on that later.
I really like King Sombra, they should of given him more time in the show. And he and Twilight never really meet.

She might be tempted.
I'm actually kind of fond of the Twilight/Sombra pairing.
Princesses or guards never helped, mane 6 always had to do all dirty work, if it was not for Nightmare Moon trying to scare them off instead of killing them, if not for Discord not being lethal, if it was not for Changelings not killing war prisoners and if not for Cadance shield holding long enough to keep Sombra away, mane 6 would be dead long time ago.
Now since Twilight is Alicorn, she can develop and study new powers, learn to fly like Pegasus, practice strength and endurance of Earth ponies and her magic limit will improve, so she can use this to protect her friends, whats more, princesses have no more excuse " we were sitting on our flanks because we wanted to see do Twilight is worth to become one of us ", now princesses will HAVE TOO protect Equestria alongside mane 6.
And because good side finally have some fire power, it mean villains can stop doing stupid mistakes, come on, the only reason Discord, Nightmare Moon and Chrysalis lost was because they had to do stupid mistakes so heroes could win, now there is no need for it since fight will be fair for both sides.
I hope that Chrysalis will team up with Sombra and some new villain and try to mess up.
Chrysalis: go my minions, today we will take our revenge for our humiliated defeat, Twilight Sparkle will pay for ruining my plans.
Discord: I see we have a party here, may I join ?
Chrysalis: DISCORD, why are you not trapped in stone ?
Discord; It is a long story and I do not fell like telling it, what you need to know is that I will not get in the way of your plans since it will cause so much chaos, but I will set up some rules, one of element bears name Fluttershy is my friend, and if you will hurt her or make her sad, I will make your invasion fall, now then, lets the game begin.
And we might see more of the princess.
As for the villians, well it is aimed at kids so they can't have the show be to dark in that. Though there's plenty of fanfic's that take a darker turn.
But I do hope Sombra and Chrysalis return.
I never though Discord was really evil. He just didn't care how his 'fun' affect others.' I'm glad he was given another chance though I though it would be Twilight who would do that. But I guess I'm not to surprised it was Fluttershy, she is the element of Kindness.
As for Nightmare Moon I think she didn't hurt the other's because Luna was still inside her.
Shinning Armor is Unicorn who alone can stop entire armies from invading and have more magic then Alicorns, Sombra for no reason was Unicorn who gained power of darkness to enslave entire empire ( crystal ponies have no horns and wings, when did they got Unicorn to take over ? ).
I think Sombra is some evil being who just took Unicorn shape, and it can explain why princesses could not kill him, why he is immortal, why he is in dark fog shape, why he need Crystal Heart to regain his physical form, because he never had physical form and he used Crystal Heart to gain one and take over.
Then Sombra arrived and used Crystal Heart to gain physical form as he enslaved Crystal Ponies, Cadance run to Equestria to ask for help, but Sombra hide crystal heart and banish empire before he is defeated.
And so Cadance spend more then 1000 years in Equestria, she is princess by title, but she have no power in Equestria and no subjects to follow her, so she just take random job to pass time and not be a burden until empire would be back.
What do you think ?
But one thing that comes to mind is she was shown in Twilight's flashback as a foal with Cadance just slightly older then her.
I just stick with my theory and ignore this mistake as animation error, because animators forgot that Alicorns should live very long and so they should not be small.
After all when Cadance got Crystal Heart, crystal ponies called her crystal princess, how could they remember Cadance if she was born not far ago, and Cadance could not just grown up in 10 years and be small for 1000 years.
He might not, but at the end of the episode his horn was still intact. It might not mean anything but you never know.
Really, well he is dark I'll try something else next time so he stands out more!!!
