Ideon
Originally a moon of Lexis V, Ideon had no notable development and little mineral wealth.
However in a strikingly extravagant (and mostly pointless) gesture, fashion designer Corinthian Blake had the entire planetoid loaded onto the Temple of Judgement and transported to Newton's World. The jump was carried out in 874, but it took nearly 6 years of maneuvering to get the ball of rock into a stable orbit.
The motivations for this move are still debated by critics and historians.
