The Empire has arrived. Their honor-bound culture wields hyper-advanced technology, while bowing to the ancient traditions of kings and queens. Now they settle the rimworld, and seek allies. Colonists can gain royal titles bestowed by the Empire. A Knight or Count can call upon the Empire's elite troops in times of need, bond with unique bladelink weapons, and wield psychic abilities.

Those who hold titles become haughty and demanding. They'll need luxurious bedrooms and grand throne rooms. They'll issue wild decrees that must be carried out. They'll make inspiring or demoralizing speeches from the throne. They'll play piano, harp, and harpsichord. They'll demand royal clothes and crowns.

About the base game:

RimWorld is a story generator. It’s designed to co-author tragic, twisted, and triumphant stories about imprisoned pirates, desperate colonists, starvation, and survival. It works by controlling the “random” events that the world throws at you. Every thunderstorm, pirate raid, and traveling salesman is a card dealt into your story by the AI Storyteller. There are several storytellers to choose from. Randy Random does crazy stuff, Cassandra Classic goes for rising tension, and Phoebe Chillax likes to relax.
