Guardian

Scar: "What do you plan to do?"

Alex: "For now, I need to see with my own eyes, then I'll have to think of something."

Scar: "Then we'll have to go to the hunting area."

Alex: "Hunting area? Is that where they usually hunt?"

Scar: "No, it's where we hunt them!"

Alex: "You hunt them, why?"

Scar: "As I said, they attack everything. The hunting area used to be a place where we gathered fruits, the best fruits are there. It used to be very peaceful, but now we have to kill some of them to feed ourselves. That's why I started calling it the hunting area, since we basically hunt them for fruits."

Alex: "I see, but I wanted to know about the areas here."

Scar: "What do you mean?"

Alex: "I want to know more about the geography; it could be important to devise a strategy, and there might be some resource that could be causing this."

Scar: "Hmm, there's nothing significant, just trees everywhere. Basically, it's a tropical forest."

Alex: "Have you found any caves or strange plants?"

Scar: "Caves? Ah, there's one, but I don't recommend you go there since there's another guardian there."

Alex: "Guardian, do you mean a giant crocodile?"

Scar: "No, guardian is the name I gave to animals that are too big, as it seems they're guarding something. I started calling them guardians. I know five of them, now four since you killed one."

Alex: "There are four more like that crocodile? What are they like?"

Scar: "Well, the one in the cave is a feline, I don't know what species it is, but it looks like a leopard or jaguar but about 4 meters long. There's another one that lives near the clearing; it looks like a giant ox. Then there's one that lives on the other side of the forest in the desert; it's some kind of giant worm or caterpillar. That's why I doubt your theory about it being Earth's past; I don't think there was a creature like that. And lastly, there's one that I'm not sure is a guardian, me."

Alex: "Wait, you? And there's a desert with a giant worm on the other side of the forest?"

Scar: "Yes, the reason I think I'm a guardian is that I'm very different from the others. I'm more than twice the normal size, and I think I'm still growing. If I keep growing, I'll turn into a King Kong or something like that. And yes, there's a desert after this forest; I've explored this whole forest, so if you want, I can be your guide."

Alex: "I see, can you describe this worm?"

Scar: "It was big, very big, I think twice the size of the crocodile. Its color was red, and it had a mouth with many teeth; I think they rotated inside its mouth, like a grinder."

Alex: I was stunned; I think if someone had said there would be something like that before, I would have told them to stop watching so many movies.

Alex: What the hell is this?! A giant, red worm with rotating teeth? Am I really not on Earth? Then where am I? A creature like that wouldn't have gone unnoticed.

Scar: "Hey, are you okay?"

Alex: "Yes, I mean, I'll be, but I think my theory wasn't right; maybe yours is more correct in the end."
