One half of the Dawn of the Emperors, and deserving of its own book by itself, Thyatis is a dying empire trapped in a cold war with another great empire also struggling with its demons.

Check out the scariest nation in the Known World, for both its power, its treachery and the fact it's slowly collapsing from its own corruption.
