THEMELION
The city in evening light: acropolis, great temple and theatre, the coast with ships on the right

THEMELION

A polis of people.

A city builder set in ancient Greece. Found Iolkos on the Aegean, where everyone who moves in has a name, a family, a trade and a chronicle of their own.

A game by

In-game scene, development build November 2026

Every citizen has a story

Click a house to see who lives there: names, ages, family ties and work. The chronicle records how the family has fared over the years.

Your city does not grow from building counts but from households. Losing work, having children or rising to a higher class all end up in the chronicle.

The stele shows a house from a test game in its tenth year, exactly as the game reports it. None of it was written for this page.

House of Xenon

  • Xenon43, head of household, farmer
  • Arete26, wife of Xenon
  • Praxinoa12, daughter of Xenon
  • Polemon7, son of Xenon
  • Stephanos64, relative

  • Doris53, relative
  • Agariste38, relative

A city that lives from its people

Residents who look after themselves

  • They fetch their own water and food, and you see them walk to the well, the market, the agora and the theatre.
  • Olives become oil, wool becomes cloth, grapes become wine. Add honey, fish, pottery, cheese, bread and bricks.
  • Contentment decides who moves in and who leaves.

Classes, offices and elections

  • Four classes with their own homes, trades and demands: Thetes, Mesoi, Euporoi and Aristoi.
  • Schooling, scholars, medicine and illness shape daily life.
  • The archon leads the city from the palace. Every five years the bouleuterion decides whether he stays.

Trade across the Hellenic world

  • Nine poleis on a map of Greece, reachable by land and by sea.
  • Relations you tend or neglect. Envoys bring requests.
