One tribe has found a harsh but harmonious existence under the oldest sun. Their warrior young are raised alongside the sun's offspring in the sacred spawning pools. The few that survive to adulthood among the voracious brood do so by learning from the sun's infants.
The grown warriors become masters of stealth, developing power over the light, bending and shifting light beams to hide in plain sight. Their garments are woven of valuable prismatic fibers, which help the warriors remain invisible in both the darkness and the light.
