Aarde was a mythical planet supposedly located deep within the ancient Sith Empire. It was only given passing mention in the holocron of Sam Sinays, but was explored in slightly more detail in the holocron of Ater Phasas'a's. For reasons unknown to even Darth Wyyrlok, Darth Krayt believed that Aarde was of great importance and greatly sought to know its location; although, without possession of the holocrons themselves, he could not find the planet. By 242 ABY Aarde had still not been found.
