A hidden portal outside your town opens into the land of Thirin — a realm that has been waiting for you specifically, according to a prophecy that names you as the god-like leader destined to bring peace to this world. Your tools are powerful towers and upgradeable weapons. Your challenge is defending your newly inherited kingdom against forces that seem determined to bring it down. Something about the land itself is on your side: it can reset time, allowing you to revisit encounters, correct your tactics, and try again until the approach works.
