Mazukata's Holiday is a small world with a dense atmosphere. Its surface gravity is only 3.5 m/sec^2, but the atmospheric pressure is almost 1.5 atmospheres. The surface is 80% water. It is tidally locked to its primary. In the endless daylight the hot pole, the temperature often almost reaches 65 C, while at the eternally dark cold pole, the temperature rarely rises above -50C. Only the depth of its oceans prevents them from freezing to the bottom in the vicinity of the cold pole. The majority of the habitable equatorial landmasses are a series of large islands and associated island arcs, with a total land area of slightly more than 7 million square kilometres.
There are only two other planets in this small system. In the next orbit out from Mazukata's Holiday is Graymalkin, a small dense, heavily volcanic mineral rich world with an atmosphere composed largely of methane, carbon dioxide, and sulfur dioxide. The final world, Boreal is a medium-sized gas giant circled by the usual collection of small icy and rocky moons.
Mazukata's Holiday is well-known for the flying clades the Virds and Vats, and for the intriguing structures on the nearby world Greymalkin.
