Crystal pony general: I'm afraid so, Your Highness. They fought fiercely towards our forces and they have enter our land.

Shining Armor: What about our allies? Are they coming?

Crystal pony general: We still haven't hear from them, Your Highness. We just hope they will receive-

Suddenly, an officer ran through the door as he said to them.

Crystal pony officer: Your Highness! The allies have encountered the Empire forces!

Crystal pony general: What?!

Candance and Shining Armor are shocked they have encountered the Empire forces.

Shining Armor: Tell me what happened?

Crystal pony officer: Abyssinia was devastated blow when they used some kind of deadly superweapon that caused the city to be obliterated. They force to surrender and they took it.

Candance: Oh my Celestia...

She was feeling terrified of what kind of weapon that Empire of Reborn Sun have created.

Crystal pony officer: Panthera tried to defend themselves, but the Empire is too strong and too advanced they have to surrender. The Changeling Kingdom have established the defenses around their area and they allow refugees to stays there safely. Yakyakistan has able to push back the Empire forces with major resistance, but it cost so many warriors to die. Prince Rutherford cannot come to aid us when there's more enemy forces coming back with full numbers. Hippogriff, Principility Equestria, and Griffon kingdom are coming to aid us, but there were stopped by Empire overwhelmed army and they're taking so much time to get here.

Shining Armor: In other words, we are losing the battle.

Candance lowered her head as she feels that her empire won't survive and even they put up the resistance, they would be countless death of her people fighting against the stronger invaders so she come up a decision and she said regretfully.

Candance: I have no choice. We must surrender.

Everyone, including her husband are shocked to her words.

Crystal pony general: But, Your Highness!

Candance: We have to survive for our people, general. I don't want to see my people being slaughtered mercilessly by the invaders that we cannot win. Give the call, general. Tell them well have unconditional surrender.

A general was hesitated, but he knew it is the only to ensure the survival of his people, so he nodded and leave the room. Everyone leaves the room as well except Shining Armor as his wife said to him.

Candance: Shining Armor, I want you to go with our daughter.

Shining Armor: What? Are you saying to stay here and be held prisoner.

Candance: It's the only way, my prince. I-I don't want to let them harm our daughter. And I don't want her to hear about our deaths. One of us has to be there.

Shining Armor: Candance, No! I won't allow it!

He said as his tears coming out from his eyes that he'll never leave her side. Candance embraced him as she wrapped her arms on his neck. She said to him.

Candance: Please, for the sake of our daughter and our future of the crystal empire. I promise, one day, we will be free soon.

Shining Armor: Candance...

He said before he hug her back. After they hugging each other, Shining Armor says goodbye to his wife before she kiss her on his cheek and he ran off headed to Principility Equestria. He knows that she will surrender herself to promise the invaders to never harm her subjects and they'll live peacefully under their occupation. He wipe his tears as he keep running until her reach to the carriage. He flies awa from the Crystal Empire, never look back and going to Equestria.

Onoda: I am general Hidehisa Onoda, I see you ready for unconditional surrender, Your Highness?

She sighed sadly as she was regrettably  going to say.

Candance: Yes... The Crystal Empire has no match against your empire, Gen. Onoda. As the ruler of Crystal Empire, we surrender to your kind and I'm hopefully you promise to never harm my subject using such brutality methods. This Empire is yours to care.

Onoda: Good...

He said with an evil smirk on his face. She hope out her throne room and take off her crown from her head. Her royal guards are lowering their spears and helmets with their defeats. An imperial warrior put the chains on her both hoofs as Candance is now the prisoner of Reborn Sun Empire. Onoda sits on the throne room as he smiled to see the victory of Reborn Sun Empire.

Onoda: Gentlemen, The Crystal Empire is ours!

Imperial warriors are shouted 'banzai' as victory to claimed the enemy nation as their own. Candance was sadly defeated and she look away with her eyes closed.

...

The flag of Reborn Sun Empire is raising on the flagpole as the flies on the air. Showing the Crystal Empire is now control of Reborn Sun Empire, the Empire army are shouted for victory. The crystal ponies are showing fear from inside their homes as they watched them cheering of victory. They let out 'banzai' sound with their beam katanas raising to the air. The Crystal Empire is no longer independent nation, this is now the property of the Empire.

...

At the distance, King Sombra watched the empire has fallen to the another empire thhag they conquered. He clenched his teeth because he wants to rule crystal empire with fear of darkness, now the Empire of Reborn Sun has taken from him. He calm himself to maintain his plan to fight against the Empire and rule the Crystal Empire for his owm goal.

King Sombra: Soon, I will take that empire from another empire and rule it as my own. They will understand why I will rule in fear.

He said as he turn into a dark shadow form and make it disappeared from the scene.
