Far future beings tapping the supermassive black hole at the center of the Milky Way for energy, as a Kardashev III civilization. This is my dream house.
Great work, love the monoliths and accretion disk. Reminds me of those depictions of heaven, with the clouds and such.
This is definitely my favorite one of these. I figure any civilization that advanced is going to have aspects to it that look straight-up fantastical. I imagine some kind of magnetic or other fields are shaping the clouds in the disc into organized machinery for some unfathomable purpose before releasing it again. And then I guess the 3 entities in the lower left have finished their business here and are off to somewhere else.
