Aemos
Far from the cluster of planes that included Eclat and Atla, there is a plane formed entirely of crystal, with great shining spires of multicolored rock reaching up toward the sky.
Even the beasts of the plane are formed of crystal, small insects scurrying around like jewels with limbs, birds that shine and sparkle in the light of the pale white light of the dim star, swooping down to catch those very same insects.
Great herds of horned beasts of darker colored crystal, stampeding across the sweeping plains, reflecting in the mirror-like surface.
And even larger and more fantastical creatures, ferocious predators, with teeth harder than the finest diamond, that shone even more spectacularly than the finest gemstones, stalking the mirrored plains.
