Black Rose Empire
At roughly 150 kilometers northwest of Sunpeak City, a group of twenty blue-skinned Celestials appeared in the sky, hidden above the white ocean of clouds. It was not the first time they had been here, and they didn't plan on it being their last either.
If one had a closer look, the blue-skinned Celestials were actually moving around on solid clouds. Moreover, various facilities and infrastructure were found hidden within the clouds.
This particular cloud region did not possess the usual properties of clouds; it was more like solid land, and given the magnitude of its size, it was no different from a floating fortress.
It wasn't the only of its kind but one of several remnants of the lost Etherean civilization, which the Celestials had found when they first occupied Pangea.
After countless moons, the remnants of the Etherean civilization had been completely absorbed by the Celestial Kingdom.
