Fiction:Time Galaxy

Time is an old, very flat, very empty galaxy. many of it's stars died long ago, and it's spin increased until the gasses were no longer concentrated enough to produce stars. It still has stars, but they are all in the center of the galaxy, all 5 billion of them, out of what was once believed to be 500 billion or so that it once contained. The entire galaxy has developed into a single, massive nebula shaped like a spiral. Over time, the gasses have slowly changed into a greenish color, making travel through the galaxy creepy, like walking through a graveyard on a misty night with green mists... in the endless nebula, you can find dead planets and ships, the ruins of civilizations that once lived in the galaxy, but slowly died out at the stars faded and died one by one... now, only the Guardians of Time's Gate remain there, guarding the mighty gate at the center, a gate said to be responsible for the galaxies demise, and for it's strange coloration. A gate said to be able to rebuilt time itself...
