or at least destroy the country of stone? reading the comments above, I'm disappointed that I did not kill him
He knocks his brother out of the story for quite some time, not dead. Takes over country of stone, not destroyed. Kills most of his opposition while doing so though if that helps. The overarching arc kinda has similar results to Against the Gods in that the MC basically rules his home realm before ascending on to the higher ones. You'll have to be satisfied with that.
