The wedding was underway, as a black cloud made its way to the dungeon were Chrysalis was being help.

“Well, well, well if it isn't Chrysalis.” Sombra said Re forming in front of Chrysalis.  

“What do you want?” Chrysalis asked.

“I want you to join me, lets work together to enslave equestria.” Sombra said opening the cage door.

“No.” Chrysalis said to him. “Prince Dillan said he would give me a fair trial, and I want to fight him again but not as enemies.”

“I guess I don't have a choice then.” Sombra said with a grin, as he charged his horn.

“Wh-what are you doing?” Chrysalis asked with fear.

“You'll see… or rather… you won't, nor will you remember.” Sombra said.

“somepony help me.” Chrysalis said with her hive mind.

{Dillan`s point of view}

The wedding is just about done, and in order to insure nothing else happens Aunt Celestia had Discord put up a barrier mixed with shining armors. When the wedding had concluded a monotone voice  range through the throne room gathering: the elements, the CMC, Discord, My mother and Aunt, and Screwball.

‘Wilder Dillan a message has been intercepted.’ The ultimatrix stated.

“What kind of message?” I asked.

‘It is from the hive mind of queen Chrysalis.’ The ultimatrix stated.

“What?” I said in disbelief.

“I knew we couldn't trust her!” Rainbow dash shouted. “She must have surrenders in order to infiltrate the castle again after you reviled her!”

“What makes you think that?” I asked.

“What makes you think otherwise?” She countered.

“The fact that we don't know what the message is yet.” I responded as I projected an image of an anthro Changeling and slammed down the ultimatix. My Anthro changeling form was well built:  I had medium sized muscles, a long black horn, four see through wings on my back, and bright blue dragon like eyes.

“somepony help me.”  I heard Chrysalis say. “Chrysalis what's wrong?”  I said using the hive mind.

“Dillan? How?” Chrysalis said.

“Ill tell you later, now whats wrong.” I said again.

“Dillan, be careful it's Sombra he's in the castle and he`s here I think he's going... to

…” The message was cut off.

“This is bad.” I said.

“I knew it she did lie to us!” Rainbow yelled.

“No… It was a call for help.” I said.

“Um… isn't that what rainbow said?” Fluttershy asked.

“No, It wasn't that kind of call for help.” I said turning to fluttershy. “She said that Sombra was in the building.”

“What!?” They all yelled in unison.

“Yes,... And I think he got to her.” I said with a grim face.

“You got that right.” A voice sounded.

We all turned around to see Sombra, and Chrysalis standing behind all of us with the entire changeling hive.

“Chrysalis.” Sombra said.

Chrysalis opened her eyes to reveal her eyes were green, and her pupils were red with purple smoke escaping like tears.

“Attack!” Chrysalis yelled.

“Chrysalis Stop!” I yelled making her freeze.  “You can't let sombra control you!”

“She can't hear you.” Sombra said.

“Then I'll make her see reason! In accordance with the treaty signed by all of the royals of one thousand years ago which includes YOU, and Chrysalises ancestors. I challenge you and Chrysalis both to a duel and if I win you release Chrysalis and leave canterlot alone, and Ill be obligated to do with you what I wish.” I said to Sombra.  

“And If I win?” Sombra said.

“You may do what you wish.” I said drawing gasps.

Sombra smiled evilly. “Deal.”  He said shaking hands. (Sombra is also anthro, I can't think of a good design so think what you want)
