Caspar von Bergliez is the second son of Count Bergliez, a famed military general who has led a number of successful campaigns for the Adrestian Empire, most notably the subjugation of Brigid in 728 in retaliation for the Mach War. As the second son, Caspar is unburdened with the responsibilities of noble rule, and as such he attends the Officer's Academy with the intent to hone his strength and become a fighter worthy of succeeding his father. He has been close friends with Linhardt von Hevring from a young age, their fathers being old friends themselves.
