The Fifth Era: Starlight Awakens

In the distant past, as primordial Earth emerged from chaos, five high-dimensional alien races descended like creator gods. Using genetic engineering as their chisel and the evolution of civilizations as their game board, they forged five generations of human civilization on the fertile soil of Blue Star. The first four civilizations all ended in failure and destruction, and the disappointed [gods] departed one after another. Now, after countless trials and tribulations, the fifth generation of humanity still thrives with life. Can they break free from the fate of serving as a laboratory for high-dimensional civilizations and shine with a light of their own on the cosmic stage?
