Civilization Barbarians: A 4x Lit Novel

I never expected to become a disembodied spirit running a civilization One night I fell asleep, and a dinosaur wizard offered me the choice to become the ruler of a tribe of people who'd just gotten to the middle of the stone age. It would be my job to guide them from these inauspicious beginnings to glory and greatness.Of course I signed up.Barbarians keep attacking, and they are literally cannibals, I can't talk to anyone directly so I'm getting lonely, and I'm terrified that I'll make a mistake, and everyone in the settlement will die horribly. But still, this is way better than any video game.
