This is an interpretation of the Palace of the Earth Spirits that is infrequently expressed in fanart. Rather than a cold, alien demesne lined with checkerboard tiles and luminescent mosaic patterns, this is a warm, cheery home.

Where does the checkerboard thing come from, anyway? Is it, like, the background in SA Stage 4?

Most likely, sometimes people include stained glass windows on the floor too.

Well, I guess it's a lot warmer now that Koishi and Okuu are back.

Why are you worried Okuu, you have the strongest card in the game!

That's probably what it is to them, cultural differences and all. If they're used to spending time underground, at the species level, then it being so dark is understandable.
And some rooms would be like this, others would be like that. It's all about the location and the inhabitants.
