The one wearing the red with the curved sabers is from the Nevxy people, who live in a moderately warm climate. As they're engaging in physical activity, they wear only bottoms. They carry curved sabers (my personal favorite), using one to direct the straight sword away and dive the other one in from above. The one wearing the white, purple, and blue comes from the Azhani people, who live further north in a colder climate. They use straight swords of medium length. I imagine that the context of this image is most likely a duel between travelers.
