Espirion was a planet in the Inner Rim Territories that was home to a sentient species. Although heavily militarized, Espirion was a known haven to refugees and wanderers, to the point that its natives engineered micro-ecologies to accommodate exotic lifeforms.

From space, the Inner Rim Territories planet Espirion looked like a pale blue sphere marbled with faint pinkish veins. During at least some parts of the year, the sky appeared deep blue from the surface of the planet. Espirion housed at least one city, whose skyline consisted of gently curved white buildings. A number of specifically engineered micro-ecologies coexisted on the planet.
