Shu is the S-Class moon of Ra Re, discovered in 2091. It contains radioactive rocks and a frozen ocean of the substance known as ice 7 as well as an unknown gas trapped in the ice crust. There is also an undiscovered type of salt that was found by a trace orbiter that was sent to analyze the compositions of all the planet’s in the Adephaga system. A landing mission is being planned to take samples of the salt and take it back to the research station around Hell'OBen for examination.
