Srisza was, as almost all Lizardfolk are, born amongst his kin in a secluded, swampy tribeland. He grew quickly, as his kind do. Along with his physical growth, grew the reverance his tribespeople had for him. See, Srisza was special. Not only did he possess a unique bodily variance that drew attention to him in the form of his blackened hide, he also grew very well into his role as a tribal warrior. Younglings that possessed the prowess that Srisza displayed from such a young age very often became one of the heads of the tribe. And so it seemed that was his destiny, even from youth.
Except, it wasn't.
Srisza was outgrown. Alongside him grew another young tribesman, and at every milestone the two of them clashed - and at most milestones, Srisza was bested. Eventually, the two grew into their tribal roles - and Srisza was deemed, simply, second-best. This was, to Srisza, unacceptable. Even if it seemed to be destiny, even if it seemed he could never beat his childhood rival, he couldn't admit defeat. He a hunger. He needed to be strong. He didn't know why he needed or wanted it so badly - whether it was for himself or for others - but he wanted it nonetheless. And this led him to abandon his tribe.
From that day forward, he sought only to strengthen himself - even if it was by unconventional means. Reading was one of such means. Through literature and a self-bestowed education, he learned many things that he never would have among his tribespeople. This led him to grow into a sight for some - a relatively well-read Lizardfolk.
Somewhere along the journey of his make-shift education, Srisza found.. religion, in a way. His searches found him stumbling upon the works of priests and clergymen who mentioned and revered one individual monichered "Gorius". While Gorius was a being of apparent benevolence, valuing the principles of light and humanity - which Srisza viewed mostly neutrally - he was also the God of War, and hence, strength. With such a discovery, Srisza wasted no time in learning all he could about this "Gorius" - which led him on an enlightening path. Over time, Srisza grew to revere Gorius as well, but not because of what he was - that being a God - but because of who he was.
This path led Srisza to become who he is today. A reverer of strength and warrior-philosopher, of sorts, beholden to the graces of Gorius.
