The Cupid Homeworld, or just the Homeworld, is a parallel universe.
Discovered (or possibly created) by the Crew of the Copper-Colored Cupids and their Creatrs, the Cupid Homeworld is a dimension of semi-solid fluffy clouds and blue skies, which they use as their home base, traveling to other universes aboard Fog Ships. It is the location of the Cupid Parliament and of the Cupid Intelligence Institute.
Behind the scenes
The Cupid Homeworld was first seen in the comic Why Doth Love Sting So?.
