'''Eiro''' is the lone [[natural satellite]] of a planet in the [[Ectanus 45 system]] and a [[human]] [[Human colonies|colony]] world of the [[Unified Earth Government]], located along the edge of the [[Inner Colonies]]. Eiro is tidally locked to the planet, though a narrow, gray-blue "twilight ring" along the moon's equator supports a small human settlement, with one [[communications satellite]], two transport ships, and very little defensive capabilities.{{Ref/Reuse|itf248}} The temperature within the twilight ring could be as high as 75°F (23.9°C), while the dark side of the moon just outside of the twilight ring could be as low as -50°F (-45.5°C).<ref name="itf251">'''Halo: Fractures''', "Into the Fire", ''pages 251-258''</ref>

Though the planet the moon orbits is unsettled, Eiro has a small population. During the war, {{Class|Halcyon|light cruiser}} {{UNSCShip|Roman Blue}} crashed onto the surface of the moon, approximately fifty-six kilometers away from Eiro's lone settlement on the dark side of the moon.{{Ref/Reuse|itf248}} In [[2557#January|January 2557]], [[Rion Forge]] and the crew of ''[[Ace of Spades]]'' traveled to Eiro to salvage the remains of ''Roman Blue'', though they were forced to retreat when they were attacked by an unknown opponent while searching the decrepit [[warship]].{{Ref/Reuse|itf251}}
