The twin beings spun, to stare at a shocked Spike, who was carrying a plate of cookies. Heavy blinked, before taking a slow step forward.
The dragon, in turn, took a step backwards, and looked ready to run, until Twilight spoke up.
“Spike, this is… would you prefer Misha or Heavy?” The alicorn asked, turning to the mountain of a man.
“I do not mind, but most know me as Heavy. I am used to people using that as my name.”
“All right. Spike, this is Heavy. I managed to summon him by accident.” At this, the mercenary looked down at his feet, noticed the circle, and gave a soft chuckle before looking back at the fire lizard. “He won’t hurt you. Will you?”
“No, I will not, if he is your friend. Though, you may need to be careful with introducing me to beings of blue coloration.” At the others’ odd looks, he explained. “Where I come from, fighting is essentially my job. Those I fight wear a blue uniform, as a contrast to my red, and it has become an instinctive reaction for me.”
“You’re a soldier?” Spike asked, speaking for the first time.
“No, that title belongs to my ally and friend. I and the rest of my team are mercenaries.” He responded.

“So, where do you come from? I don’t recognize your species, and you certainly don’t seem like a demon, so that rules out most of the options.” Twilight inquired.
“I am a human, and according to Engineer, an entirely different universe.” As Spike and Sparkle drew breath to exclaim, he held up a hand and continued. “And I suppose you could call some of the powers I have demonic.” He balled his upright hand into a fist, and red lightning bounced around it suddenly, giving it the appearance of glowing. The purple aliens gasped, and as he released his grip and the energy faded, Twilight was already talking. “What was that?!”

“We call it Critica. It’s formed by the unique magical energies contained within our weapons rapidly ionizing the air, and the electrons stripped away hitting other, previously ionized atoms, allowing them to fuse and immediately re-ionize. Normally we need a catalyst, like the Kritzkrieg, but it seems the ambient magic field of this world acts as an automatic catalyst, to be used when needed.” He explained. Spike was lost, but Twilight was taking mental notes at light-speed.
“Th-th-that’s incredible! What effect does it cause?”
“It increases their ability thrice over.” Heavy replied, lowering his hand. “I would like to meet your friends, perhaps?” Twilight blinked, then shook her head.
“Maybe we should tell Princess Celestia about you first?” At Heavy’s responsive nod, she lit up her horn, levitating a nearby notepad over, earning her a curious look from Heavy, scribbled out a note, and gave it to Spike to send off, which he did.

Almost as soon as the last wisps of flame vanished, a burst of golden light erupted in the middle of the room, and as it faded a white alicorn was left in it’s place, horn still glowing. Upon seeing Heavy, she lowered her horn at him in a battle-ready stance, to the confusion of the others.
“What are you doing here, human?” She asked, in a low, almost hissing voice. The big man dropped his hands to his sides, and faint wisps of Critica began forming.
“I came here as an experiment being performed by my friend. I manifested as a summon by Twilight Sparkle.” He replied calmly. Celestia didn’t move.
“And what was this experiment?” She asked.
“We were attempting to see if interdimensional travel was possible. If you have had negative past reactions with humans, remember that I am not they. I did not even know your world existed until less than half an hour ago.” He answered.
Celestia relaxed, and raised her head away from the threatening position, but her magic glow didn’t fade and her wings didn’t drop. Heavy released the lightning in his fingertips.

“Very well. I have met two different kinds of human before. One kind were space travellers, and a great battle ensued. The other were kinder, but you look more akin to the first. Shall we try and start over?” Heavy nodded.
“Yes. I am Mikhail, or Misha, but I am more accustomed to Heavy. And while I am a fighter, I have no ill intent towards you or your people.” He said, with a respectful nod. She returned it.
“I am Princess Celestia, also known as the Solar Diarch. I care much for this land, and am willing to go to great measures to protect it, even if they fall on the far side of morality.” She stated.
“That is good. A ruler should be prepared to do what is wrong, as long as it does not become a habit.” The Rushern said, before turning back to the shocked Twilight and Spike. “Shall we go meet your friends now?”
