Xelaya was a member world of the Planetary Union, home to the Xelayan species.

The planet was wildly considered to be one of the most beautiful planets in the entire Galaxy. Its landscape contained modern cities with glimmering skyscrapers, and a significant amount of untouched natural habitats, beaches, and large oceans. The sky gave off a natural purple hue that spread over the entire planet.

Xelaya's gravitational pull was many times greater than the planetary average. Living creatures like Xelayans and eevaks had power and strength many times that of species from other worlds. Visiting species, such as Humans, survive on the planet only through the use of special protective technologies like environmental suits and gravity shields.
