A colony mission was sent to this system by the Terranova Foundation. A Greater Way Daoist colony was found at LTT 1445 A, which they called Qingcheng, but they did not attempt to make any claims to the system and were left alone. The colony decided to go for League membership rather than remain tied to 82 G. Eridani.
