T. K. Arispe

 One last character design, for Yonwin! He was so fun to write in Earthkeepers and I think he probably had the most compelling character arc. After (spoilers) helping save the world and becoming the second-youngest Graling in history to earn a warrior's title, Yon has grown from a shy, insecure teen hiding in the shadow of his famous aunt, to a confident warrior, now quite famous in his own right, and secure in the fact that he loves both combat and technology. The Apparats made him a fancy high-tech spear and shield, but I imagine when Yonwin competes with other Gralings, he uses old-fashioned equipment to keep things fair.

It's not really mentioned clearly in the books, but Graling warriors train to specialize in two weapons, generally a long-range and short-range, respectively. This gives them more versatility on the battlefield, and also ensures they can keep fighting if something happens to one of their weapons. Fraa's weapons of choice are a long knife and a throwing club.

Gralings sound like terribly violent creatures, but they're physically hardier than humans and can take quite a licking with no lasting repercussions. That may be part of why they find combat fun, and make a point of organizing battles that are inversely proportional in scale to how serious the issue is that the battle will decide.
