The lands of Letorni were a chaotic mess of sudden climate and environmental changes. With this, the first settling lambs had to learn to make sense of the chaos quickly. And with that came a select group who mastered the forces of logic and the scientific process.
Physically, Letornians come in many shades and hues, but a common trait among them seems to be their bleached hair. According to rumors, this was due to a side-effect involving a past over-exposure to Lexical radiation during the Great Spark.
Letornians are typically referred to as the tinkerers of humanity, and many are responsible for the emerging push towards technologically and automation.
