T'ien Ch'i is a human civilization based on pre-modern China, available in all three Ages. It may refer to:

• EA T'ien Ch'i, Spring and Autumn ← This one has flying Mages, ancestor worship, and tumultuous Demons and Warlords.
• MA T'ien Ch'i, Imperial Bureaucracy ← This one has Feng Shui, wizened Alchemists, and capable exam-picked Bureaucrats.
• LA T'ien Ch'i, Barbarian Kings ← This one has been taken by Mongol-like riders, who have brought in their Shamans.

All three have basically the same infantry, which is impressive in the Early Age but not so impressive in later Ages.
