The Younger Races are civilizations who have only developed relatively recently in the history of the Starmourn Sector and were predated by the Elder Races. They rose to prominence after the War of Extinction that left almost all of the Elder Races extinct at the hands of the Ishvana ushering in the Younger Era.
