War Across Time

We never should've done this. I knew it from the beginning that time is not to be messed with. Those birdbrains seemed to be less advanced than we are, but they definitely had the advantage of time. They could attack us 70.000.000 years before we could. And they did. God, and how they did.

Yeah, at first it seemed like a good idea. Travel back in time to the Cretaceous, build colonies, seeing plants and animals again. Even though they were not the animals our ancestors knew, but dinosaurs. But even that seemed cool. I loved dinosaurs as a child, which child doesn't love dinosaurs? The thought about a blue sky, green vegetation and non-synthetic food seemed to good to be true. Well, maybe it was...

Some scientists raised concerns. Wouldn't this affect our own past? The answer was no, it's a different timeline. Well, technically, they were right. Technically...

We didn't expect intelligent life in our destination. But that seemed even more awesome at first. How could our paleontologists miss out a full blown civilisation from the Creatceous age? Maybe buildings and technology don't fossilize well. I don't know, I am no scientist. I am a soldier. Why did we need soldiers?

Maybe it's in the human nature. Oppressing those who are weaker than we are. Isn't it what we always did? Europeans took the land of other cultures, humans wiped out thousands of animal species, it's just they way we always were. It is even the reason why we had to leave our time in the first place. To late did we realize that we needed the animals. But this time, it backfired even more than before.

Sure, they had electricity and firearms, but they stood no chance against our plasma weapons. Not long after, we had our colonies where their cities used to be, and those birdbrains we didn't kill were on the run. But we didn't take into account that the weren't just more primitive than we were. They were different, and in some fields, their technologies were better. For example genetic engeneering...

We should've noticed when the small mammals started to die. But we didn't care. Who cares about rats? The plague, whatever it was, didn't affect humans, so it wasn't of our business. But it affected all those mammals that lived in the shadows of the dinosaurs. When we realized that it was their doing, it was already to late.

What we noticed was something else. At one point, the reinforcments failed to appear. Soon, the birdbrains outnumbered us again. They breed faster than we do, grow up more quickly. For years, we kept asking for reinforcements but didn't get any. Nobody who traveled back to our time to see what happened ever returned. But some of us already knew what happend. What the scientists never told us was that we could only contact the future we created, not to the one we came from...

At the time of this writing, only one human colony still exists. We're the last humans. We're the only humans that ever existed in this timeline. I don't know who or what will read this journal. I don't care. Who knows what will follow, but certainly it won't be human, or even mammalian... "
