Nul I is a mesoplanet in the unclaimed Nul system, and is the closest planet to its star. In 2510, a research team funded by the University of Persei established a research base at the bottom of one of its deepest craters in order to study how the planet's environment was affected by the temperature and radiation fluctuations in its sun. However, after repeatedly losing their sensors and equipment to thieves, the team's funding was cut and the station was abandoned.
