Big Yin is the informal name for the first variable daylight region of Slab. It doesn't have an official name due to the irreconcilable conflict over what language the name should be in. However as it is home to MultipliCity and The Valley few refer to it by name anyway.
It is illuminated by a continuous sunstrip which cycles from full daylight to full moon every ten hours and has a mild autumnal climate.
