Andromeda

A sudden burst of mysterious energy wafted throughout the universe, emanating from an unknown source... Suddenly the energy drew in many planets to their (seemingly) doom! The planets that were sucked into the energy were transported through space, set into an orbit around a massive star... The planets were far enough away from the star to survive without issue but were suspiciously put close enough for travel to be possible between the planets. There's no way all of this happened on chance... Someone had to have planned this.
