History of the Milky Way Galaxy
The First Golden Age - ~100 Billion YS - ~89 Billion YS*
Or ~14 Billion YAR - 3 Billion YAR**
At some point some about 12 billion YAR, the first races began to touch the stars. They advanced in spurts and starts, and after a few billion years, reached a level of technology that would remain out of reach of the rest of the universe for billions of years to come. The wars these races fought were devastating, and after a particularly deadly one (supposedly several races were wiped out in one battle), the most advanced races decided to stop this mess. They created the Galactic Treaty and the Keeperage system. The Keepers were tasked with ensuring that the Treaty was obeyed and bringing the younger races up. But knowing that they couldn't live forever, the Ancient Keepers (as they were called) created special "seals" where their most powerful technologies and ideas were locked away behind a code. These seals were then passed down to the younger races that the Keeper felt would weld the power best. The system didn't work very well, and after peaking 3 billion YAR, the Keeperage system collapsed from 500 races to two.
