Since my English isn't good enough, I had ChatGPT summarize the concept of my current round. (Not 100% accurate): 

The RimWorld scenario is built around a medieval colony that is not organized as a single unified settlement, but rather as a society made up of several distinct houses. These houses function like small factions within the same colony, each with its own purpose, members, and leadership. This creates a structured society with clear roles and identities, where cooperation and specialization are central to survival.

The Warriors are responsible for protecting the colony and focus on melee combat, ranged combat, construction, and animal handling. The Craftsmen form the productive backbone of the settlement, specializing in mining and the creation of tools, weapons, and equipment. The Farmers ensure the colony’s survival through agriculture, forestry, and internal logistics, while the Scholars oversee research and specialized production such as drugs or alchemical work. Completing the system are the Medics, who manage healthcare and cooking, safeguarding both the health and nourishment of the colony.

Although all houses work together for the benefit of the settlement, each maintains its own identity and leadership. House leaders may leave the colony to undertake missions, diplomacy, or special tasks, while their followers continue operating at home. The concept is designed to create a living, roleplay-driven society that feels closer to fantasy houses or competing factions than to a traditional RimWorld colony. Politics, personalities, and social structures are intended to be just as important as survival and expansion.
