Bears a striking resemblance to the Apple of Eden from Assassin's Creed, but this passes a more magical feeling, rather than the ancient technology from Those Who Came Before. And the ruins look immersive as well!
The prosthetic leg helps guiding the memory. I was in an Assassin's Creed marathon through Ezio's history (II - Brotherhood - Revelations) back then, so the Apple was still fresh in my mind.
You are correct, naturally. Everyone sees in the image their own favourite golden orb, which makes me wonder what was your inspiration for those. Might I add that your image has its own identity, and only the golden orbs are loosely reminiscent of Assassin's Creed. The girl, temple around her and solar system give away a very different vibe. But I'm too much of an AC fan not to think about it when I see a round golden shape.
