Seguleh

The Seguleh are genetically enhanced (probably by a Primals  who was interested in creating the perfect warrior) humans who live in Segula . They occasionally leave Segula to experience the world, challenge themselves or deliver punishment to rogue Seguleh or other causes that catch the attention of the Grandmasters.
A Seguleh looks like a lean human mostly light brown of skin, dark eyes and black hair. They always wear a enamel mask in public, in which the color and markings on the mast indicate their martial rank.
Their entire society is centered around martial accomplishment, a better warrior is higher in the hierarchy and the best twelve warriors are called the Grandmasters.
