Once upon a time, there were four kingdoms: The Light Kingdom, The Dark Kingdom, The Fire Kingdom and The Ice Kingdom. The rulers of the kingdoms were good friends.
In The Dark Kingdom, King Nightmare (Shiny Umbreon) enjoyed ruling with his wife, Luna (Umbreon) and their infant son, Shadow (Eevee, in this chapter).
One day, Queen Luna took her son for walk. She enjoyed spending time with her son until a disguised Pokémon blocked their path and killed Queen Luna with Crush Claw and Slash. Then the mysterious Pokémon put a note on Luna's body and left.
After Shadow saw that, he started crying and he was standing there for 15 minutes until a young Zorua named Darkus came to him.
Darkus patted Shadow on the shoulder and said: "Are you OK?"
Shadow looked at his mother's dead body with a sad face and tears in his eyes. Darkus understood that she was killed.
A male Zoroark, was calling Darkus until he found him, when he reached the kids, he was shocked to see Queen Luna dead.
The Zoroark asked: "What happened?"
Darkus: "Someone killed the queen, dad. He or she even left a note."
Darkus's father took the note and started reading it. He was shocked to see what it says. Then he turned around and shouted: "Hey Moonlight. Over here."
An Absol came with two Bisharps, he was Nightmare's second-in-command and childhood friend. They were shocked to see their queen dead.
Moonlight: "What happened, Trevor?"
Trevor showed the note to Moonlight and said: "This note explains it."
Moonlight and the Bisharps read it and they were shocked to see what it says.
Trevor: "It doesn't make sense. He doesn't kill others."
Moonlight: "His name is on the note, so it is him. I guess he has become a foe now."
Trevor: "I don't know. We should just report this to King Nightmare. I'll carry Prince Shadow and my son will be carrying the note."
Moonlight: "Alright" He turned to the Bisharps and said: "Guards. Take the queen's body to the palace."
The Bisharp guards obeyed and took Queen Luna's body while Trevor took Prince Shadow and Darkus took the note.
After the group reached the palace, Nightmare was shocked to see his wife dead.
Nightmare: "What happened?"
One of the Bisharp guards took the note, handed it to Nightmare and said: "She was killed and the killer left a note."
Nightmare read the note that says:
Dear Nightmare
I noticed how soft, pathetic and weak you have become, so I killed your mate to prove it. Soon I will take everything you love, your subjects, your kingdom, even your son. And then me, my wife and my daughter will be the most powerful Pokémon and rulers in the world.
King Dusk
King Dusk was a good-hearted Sylveon and King of The Light Kingdom and he wasn't the Pokémon that killed Queen Luna but he was framed by the killer.
After Nightmare finished reading the letter, he said angrily: "I can't believe King Dusk would do this to me. He will pay for this with his life."
Moonlight asked: "Shall I send the guard to kill him?"
Nightmare: "No. I'll kill him myself. In the meantime you will protect my son."
Moonlight: "Don't worry about it. You can count on us."
As Nightmare was going to The Light Kingdom, he thought: "Well, since King Dusk is my so called friend, it's easy to go for the kill."
Nightmare went to The Light Kingdom, entered the palace and knocked the door on Dusk's room: "Hello Dusk. It's me, Nightmare."
Dusk opened the door and said happily: "Oh hey Nightmare."
Nightmare asked: "So, why don't we go outside?"
Dusk replied, smiling: "Oh sure!"
Dusk and Nightmare went to an alley near the Dark Kingdom.
Nightmare: "Hey Dusk. Why don't we battle like we used to?"
Dusk: "Challenge accepted!"
Nightmare thought: "Ha! He fell for it!"
Nightmare used Shadow Ball and used Crunch. Dusk was left with 1HP.
Dusk: "Good game!"
Nightmare: "You thought this was just a game, did you!? I can't believe you kill my wife!"
Dusk: "I didn't do anything to her."
Nightmare: "Letters never lie. Now die." And then he used Night Slash at Dusk.
After he killed Dusk, he returned to his palace and sat on his throne. Trevor handed him Shadow and Moonlight asked: "How did it go?"
Nightmare: "King Dusk is dead."
Trevor: "Sir, now that you killed King Dusk, his wife, Queen Shine will start a war against you."
Nightmare: "So be it. I'm ready to fight her, now that she's my archenemy. And since she has a daughter that is born on the same day as my son, she will make a great archenemy for him. Isn't that right son?"
Shadow couldn't understand what Nightmare was talking about, so he was just looking at his father with confused face.
Meanwhile at the Light Kingdom
One of the guards who is a Clefable entered the castle and said: "Y-your majesty!"
Queen Shine (Shiny Sylveon) replied: "What is it?"
The guard replied, holding Dusk's body: "Your husband, he…"
Shine sobbed, holding her child, Glitter.
The guard said: "My queen. We found a black robe on his body."
Shine: "The Dark Kingdom... I can't believe it. This means WAR." She looked at her daughter and said: "It's okay little one. I won't let this happen to you." And then she nuzzled Glitter.
