Precursors, predecessors, the legend of galaxy… Who are carrying the forebear’s genes among existing races, we can suppose only…Worlds of galaxy are everlasting, beautiful, unique and dangerous. Some of them are inhabited, some ruined and deserted, other - just a smugglers trans-shipment stations. 
Some worlds are only at the beginning of evolution, other are falling into decay. Only when you’ll pass through all these worlds, sense a heat of blazing lava-seas and chilling cold of abysses, see the stark heavens, you will realize the real power of nature. Only when you’ll meet corrupt judges, mendacious politicians, unselfish protectors and cruel tyrants you’ll understand passions of society. When you’ll reach an unexplored sectors of galaxy and come across a mysterious natural phenomenon, fly through the tail of the comet or dive into the casual portal, only then you’ll perceive the infinite depth and diversity of the universe.
