The second ship stopped at the edge of the belt. Inside, one of our robots was manning a console as we watched from the outpost orbiting Titan. "What do you mean?" we asked. "This is our first voyage."
The message that came back was... odd. For the first time, there was audio included. It sounded like incredulous laughter, followed by words in a language none of us had ever heard before. Accompanying them, however, was a convenient translation into English.
"We remember, Seluvians, even if you do not. We remember your rampage through the stars, half of a galactic year ago. Your bones shall rot on your planet, quarantined as you are. Your teeth, your claws, your scales, they shall be consigned to the planet you rotten lizards evolved on."
I grabbed a microphone and sent back a response. "Our species is far too young for that to have been us," I responded. "The earliest hominin fossils, fossils of our ancestors, are less than one thirtieth of a galactic year old."
The response was more scoffing. "Impossible. A lie!"
"Approximately one third of a galactic year ago," I responded, "an asteroid collided with our planet, Earth. By our best estimates, around seventy-five percent of all then-extant species became extinct." I turned to my girlfriend, Mary Nichols. "Whatever threats you faced, I assure you, they are most likely extinct."
"...Bring one member of your species to the point where this is being broadcast from. We shall judge for ourselves."
"I understand. Give me twenty-one days. Robots, translate that into units that would make sense to them." I looked Mary in the eye, my head craning back to meet her worried gaze.
"Lucy..." She put a hand to my cheek. "You're planning on going, aren't you?"
"I'm the one they talked to. It only makes sense." Mary's eyes began to tear up.
"Just promise me you'll be back safely," she said. "I already lost my sister. If I lost you too..."
I pulled her close, stood on tiptoe, and pressed my forehead to hers. "Don't worry. I'll be back."
Three weeks later, I was on board the shuttlecraft Aleph-Null, wearing an environmental suit in case the aliens' craft had no breathable air. "Attention alien vessel," I broadcast into the void. "This is Lucille Roddenberry of Earth. I communicated with you twenty-one days ago."
"Communication confirmed." My sensor picked up something incoming, something much larger than my shuttle. "Our craft is at the appointed location. Where are you?"
"I am currently orbiting the dwarf planet Haumea. The coordinates, relative to the sun, are here. Your sensors should be able to pick me apart from the debris field."
"Our sensors are having trouble with objects this fine," came the response. That felt... odd. Finally, however, they appeared to find me, as I could feel the ship suddenly stop moving. The orbit hadn't been geosynchronous, but it also hadn't been stationary, so... I could only assume that some sort of tractor beam or something was pulling me towards their ship.
"You may exit the ship, Lucille Roddenberry of Earth." Carefully, I opened the hatch and walked out. To my surprise, several large pieces of scrap were next to me in a cavernous cargo bay. I pressed the button on the side of my suit, which was checking the air composition.
"No deleterious effects," it finally said. "Unusually high Neon concentration, Oxygen at acceptable parameters, ammonia and chlorine unusually high but below toxicity, be warned that olfactory adjustment may be necessary." As I undid my helmet, I had to admit, I could definitely smell a weird combination of ammonia and bleach. As I looked around, waiting for the visitor, I heard some kind of garbled language not dissimilar from the one the aliens had been speaking twenty-one days before.
Suddenly, my headset crackled to life. "Where are they? I see the scrap metal, and the oddly intact box what has oxygen, but where..." At the far end of the room, I could see four of them. Their heads vaguely resembled those of a bear, while their bodies were more like someone had taught a woolly mammoth to become bipedal. They also had strange, chitinous plates on their forearms, and were wearing what appeared to be uniforms made of some fabric that seemed almost like silk — or perhaps spider silk, I amended, seeing a massive twelve-legged arachnid perched one the shoulder of one like a parrot on a pirate captain. They were looking around at eye level — which, judging by their height, was probably around seven meters.
"I'm here!" I shouted. That got their attention, and they looked around before looking down at me. I could see the surprise and confusion on their faces — after all, I mused, it would be like if my Shiba, Genji, had suddenly shouted at me in English. "Jesus Christ you're tall."
They made their way towards me. "General," said the tallest, who was wearing glasses, "this can't be the Scourge. Sure, it's bipedal — "
"She's bipedal," I interrupted.
"She's bipedal," they corrected, "but look. She's positively tiny — taller than a croxis, but that's not saying much. If she has a tail, it's completely hidden in that suit. And she appears to have a mane."
"I see," said the one with the spider on their shoulder. "Well, Lanthes? Do you agree with the doctor's assertion?" The General looked at the one standing to their right.
"Well... yeah. Kinda hard not to, General," they said. "Absolutely tiny. I don't think I've seen a sapient galactic species that small. Closest are the tvar, and they're still four meters. Not like the Scourge, who were taller than any of us." I pulled up an image on my datapad.
"Excuse me, but... is this the skull of one of your 'Scourge'?" I asked, projecting an allosaurus fossil. The group recoiled.
I shook my head. "This is the skull of an allosaurus. They died out one hundred forty-five million years ago. A little over half a galactic year. At least, that's when they stop showing up in the fossil record." I turned off the hologram. "They're extinct... and even if they had survived, the Chicxulub Impact would have killed them sixty-five million years ago."
"Hmm." The massive aliens looked at me. "And how do you know of this... 'Chicxulub Impact', then?" I shrugged.
"Archaeology. It's how we know most of the planet's ancient history." The General frowned, but nodded. "So... can we send out ships?"
The General sighed. "The Council will need to be notified. Mervel, send a message. The Scourge have been wiped out. Seluvia is no more. In its place stands a planet named Earth. We can afford to send a negotiation team."
