Af'El is homeworld of the Defel race, it is a large, high-gravity world orbiting the ultraviolet supergiant Ka'Dedus. The planet has a thick atmosphere but no ozone layer, and so ultraviolet light passes directly to the surface. Heavy atmospheric gases then block most of the remaining wavelengths of light. For these reasons, all lifeforms on the planet have evolved with the ability to see in ultraviolet light. The planet's main export is the metal meleenium. At one time, Kuat Drive Yards mined Af'El for many of its natural minerals.
