So it's Ned and Swift against farmer-boy and Jerra.
The hunters gathered in the middle circle inside the training ground. Their training was suspended for the incoming fight and they were eager to watch the fight.
With Twali's command, the sparring circle in the center shook, and with a rumble, the circle was raised for a meter high. Making it grand and fit for a fight. The diameter was enough for the fighters to move with relative ease. Short grasses sprout at the bottom edge of the circle.
Along with the mechanical sound of the sparring circle came another cranking. Another stone rose just beside the sparring circle. It resembled a box, nearly ten meters wide and five meters high, wherein people could watch the fight with complete ease. It was shaded with the stone ceiling and a hollow space in front to watch the fight.
