The Terrarian Sun and Moon

"Well then brother, we should get back to our own territories, we need to keep the biomes in check." Sol told his brother, Mon.

"Are you sure I can do it? What if I get corrupt again..." Mon said, looking down.

"Mon, that is nonsense, it will not happen again as long as we keep using the powders on ourselves, now let's get back." Sol reassured his brother.

Before they could leave, they heard the parking break of the TARDIS again. They both turn around and walk up to the blue police call box, waiting to greet their friends, who had just saved them from a gruesome battle. The TARDIS blinked into existence a small bit, then tore through a hole in space, roughly, and on accident. Sol and Mon were sucked through the hole, and had to act quickly to pull out their dual hooks to latch on to the machine and each others dual hook. The quickly latched it onto their armor, fitting perfectly into the shadow armor and hallowed armor.

"Mon!" Sol shouted, "What is happening!"

"It looked as if we are being tugged through the void!" Mon shouted back. The void of nothing and everything at the same time made their voices almost muted, so they had to amplify with their minds.

"Where are we going!?!" Sol shouted.

"I don't know bu-" Mon said, but was cut off when the dual hooks let go of the machine. They were only attached to each others hook, very scared.

They started falling into a random dimension.

"I think I just figured it out, but why this 'Equestria!'" Sol shouted.

"I think because of similarities!" Mon shouted, "They have two spirits of the light and dark who are related, seems similar!"

"Well, what should we do, Mon?!"

"I don't want to go in unarmed!" Mon shouted back. "Get out our weapons!"

"Okay Mon, I'll trust you on this!" Sol shouted back.

Mon brought out his Star Cannon while Sol brought out his Rainbow Rod. Their signature weapons.

The Rainbow Rod was literally a rainbow colored rod. It made an extremely powerful rainbow ball of pure light. It can completely destroy things with a single shot, and be shot in rapid succession. It is the weapon of choice by the spirit of light, Sol, because the light is empowered by 10 times from his power over light and the day.

The Star Cannon is a large blue cannon with a star on both sides. The stars are buttons that shoot stars right out of the front of the cannon at rapid fire speed. It's automatic, and the stars can go at 105 feet per second. The stars can rip strait through any living thing 3 times, being a destructive beast. It is the weapon of choice by the spirit of darkness, Mon, because it can shoot endlessly with his power over dark and the night.

"You ready, Sol?!" Mon shouted, reaching the portal.

"I don't think we have a choice!" Sol said, "But I am as ready as I'll ever be!"

Then they fell through the portal...

...Right in front of Princess Celestia and Princess Luna. Fully armored with armor that can block missiles. Armed with weapons that can kill deities. 10 feet from the throne.

"Well, maybe we didn't need the things. At least I don't think we do." Sol whispered.

"Quickly, take the armor and weapons into your inventory. The guards have gathered, they can't get into it." Mon whispered back.

The two spirits quickly took off all of their armor and put away their weapons, putting their hands up to show no harm.

"ARREST THESE TRESPASSERS!" Yelled Luna, and the guards immediately surrounded Sol and Mon, spears pointed.

"Oh co-" Stated Mon

"Shh!" Sol silenced.

The two spirits were brought to the dungeons by the guards and thrown in, not allowing argument.

"Well, that went well." They both said.
