Planet Nemesis NASA
Members of the Black Moon Clan are descendants of anarchists who opposed Crystal Tokyo, claiming that the governing group was corrupt and the resulting increase in human longevity by the Silver Crystal was a crime against nature. The founding leaders of the Black Moon were guided by Wiseman to the Planet Nemesis (宿敵, Shukuteki), a phantom planet that can conceal itself from anything save X-Rays and produce shards of the Malefic Black Crystal (邪黒水晶, Jakoku Suishō). All members of the Black Moon Clan have black, upside-down crescents on their foreheads (the inverse of the marking of Silver Millennium). They wear earrings which, according to the Materials Collection, are made of Black Crystal and allow them to teleport.
