The Southern Cross Constellation, core sector of the Radiant Domain, the Three Worlds and Nine Skies.
Within a cross-shaped constellation sector suitable for inhabitation and made out of twelve hundred stars, a single massive artificial object was darting through the silver Steel Continent.
It was a mobile city that resembled a saucer and was rotating ceaselessly, stirring a massive tempest around itself. A certain distance was kept between the bottom of the city and the continent, with blue fluorescent circuits circling while invisible bounded fields kept pushing it ahead—in reality, it would be more appropriate to describe it as flying through low altitudes then walking around.
