The Guardian

And man, I've been in so many weird places, but this one is uncomparable. Their system is made to not be deciphered. It's so hard to understand their duties, what is the correct place of any creature there. They seem to be recyclable. They live and die as if it's just nothing. They may even get to complete just one task and they die. Not because they kill themselves or something like that, it's just an eventuality, or maybe a predator in the same environment, or because their cycle just ended.
It's a crazy way to live. You live to serve. You live to be ephemeral. You are created from garbage, and maybe you don't even come back to that garbage, maybe you then are eaten by another creature that manages to live just 1 day and then you become garbage through him, that became garbage aswell. No one blames no one, no one says anything. They just do whatever the fuck they are intended to do from their beginning.
Well, on my way to that town back there (you can see it clearly), following that clear path, I started to notice a gigantic construction, like a piece of a purple rock, guarded by a monstrous creature. I could hear it just BREATHING from like 50 meters. It was astonishing, not in a good way. I thought that it would start moving and swinging that huge branch and that it would kill us all. But it did nothing at all. No other creature wanted to step close to that thing, and that's a fair decision.
Now I knew that my secondary goal was to get inside that building. What that thing could possibly be guarding?
