For those interested in historic roleplay in a virtual environment, the court of Versailles (of 1773) is returning from Fontainebleu (summer hiatus) in September. This is the court of Louis XV, the year before he died, when Louis-Auguste and Antoinette were still the "fils de France."
The palace itself is based on the blueprints of the original, and roleplay is strictly governed.
