The Yasuki Palaces, sometimes called the Black Crane Estates, are an impressive complex which perches majestically on a cliff overlooking Earthquake Fish Bay. The castle is the place the Yasuki claimed as their home after they broke with the Crane. It is a testament to their wealth and trading acumen, a combination of beauty and pragmatism. The castle may seem a work of art when seen from a distance, but it is a Crab castle, and as such also has impressive defensive fortifications built into its splendor. Yashiki Yashiki boasts some of tallest and most impressive towers of any castle in the Empire, allowing it to watch over not only Earthquake Fish Bay and the Tidal Landbridge, but also the nearby Crane lands. However, it also has opulent gardens and expensive art lining its walls. In the center of the castle is a shrine dedicated to both Daikoku, Fortune of Wealth, and the first Yasuki.
Much diplomacy takes place in Yasuki Yashiki, but it is usually of a mercantile sort, focused on trade agreements and tariff disputes.
