lore: Witherania got kicked from its galaxy Kelper-27b in solar system 63. and Witherania stumbled across the kipper belt. got lost ran into pluto. and he showed Witherania his new home. he showed Witherania where an orbit was needed. so I pushed murcery outta his orbit and stole it. not he's like... you could fit one titan (saturns favorite moon) between murcery. now mercury thought he had to put up with vunus's nonscence. but everyone turned their attention to me and after near killing venus and earth. I never got the space I wanted so. I took one of earths rokets that was flying past me (it was the tsar's ship) and threw it at venus in the eyr. blinding him the using murcery as a moon (or a wall against the suns solar flares)
