Era beginning/end
When the Dreidas came upon a Swahada expedition in deep-space, a new era was born of intergalactic society, a new age from then on to be known as the Galactic Age.
When both the Dreidas and the Swahada achieved full fledged space travel, both peoples sought to explore as much as they could. It was inevitable that these two curious species would meet, and thus the Galactic age was born, as was the prototype for what would be the Systems Alliance. This would also start the first era of the Galactic Age, named for a Swahada word from their history: Genesis.
