Win / Lose

Victory Conditions: Recover the throne and be officially crowned the rightful king of Asteria. Defeat, capture, or secure the surrender of the usurper, King Damian Blackwood. Gain the support of a majority of the nobles and the people. Ensure the kingdom's stability after the coronation, avoiding civil war. Keep at least one major group of allies alive to secure the kingdom's future. ☠️ Defeat Conditions: Die during the story. Be captured and executed by the usurper. Publicly renounce your claim to the throne. Lose the support of the people and the nobility until you have no allies left.
