In Four Humours, you are a doctor in medieval times, and everyone knows that your personality is determined by an imbalance of your bodily fluids, a.k.a., the four humours:

1. Choleric (Yellow bile) - Goal-oriented, decisive, ambitious.
2. Sanguine (Red blood) - Talkative, enthusiastic, social.
3. Melancholic (Black bile) - Analytical, detail-oriented, reserved.
4. Phlegmatic (White phlegm) - Relaxed, peaceful, easy-going.

The kingdom — composed of six map tiles with various locations — is filled with all types of personalities, from choleric sorcerers to phlegmatic peasants. ​Prove you're the best medieval doctor by visiting citizens throughout the kingdom so they can live out their life's ambitions...or lack thereof.
