Without giving too much away, my hero is raised as a slave in the mines. He works his way up through the ranks and becomes a guard. But at his coming of age ceremony, he's tattooed with all of the sins of his people, the underground slave society. It's considered a great honour, but he finds out he's going to be killed (it's the final part of the ceremony - to put to death the sins of their collective past). Naturally, he's not cool with that. In the process of trying to escape, he stumbles upon his father and together they escape to the surface. There, he experiences the outside world for the very first time. And that's more or less, the first part of the story. And that's where this world-building will help greatly.
Thank you, dear sister!

Oooh, this book you are writing is something I definitely want to read! Can you have it finished by tomorrow? I don't like waiting.
