In ancient times, the Lask were a warlike tribe of desert raiders who opposed the Illumian empire. Soon, however, they were awestruck by the power of the Kyuran, and willingly surrendered, in order to become Illumians themselves. The Kyuran, still bitter, keep them at the bottom rung of society.
In modern day, Lasks are usually warriors. They are the military of the Akhetan empire, but in status are just above slaves, and usually remain poor. However, the dream of almost every Lask man is to make a name for himself, and become a Dragoon. The few who successfully rise to this position occupy a unique place in society, they and their children will be in a place between the Ritta and the Kyuran in power. Most of their children end up becoming a part of the Rittan caste, the main reason why the blood of Rittans has grown so murky over the years.
If a Lask ever becomes a mage, he is trained to use magic to fight, and for no other purpose.
