Think about the tower
The tower. You think it's kinda weird how everyone's just kind of used to its existance. If it appeared suddenly one day, you're pretty sure people would think that it's really strange and everyone would be scared. But it was here before... anything. It's kind of creepy to think about it.
You wonder who could have the technology to make it, and what was their purpose with it. More importantly, why did they send someone to tell you to go to it? Why you, specifically? Why weren't you thinking about this before? Heck, you should have tried to ask the resident why it wanted you to go there in the first place!
