In the beginning this was just a big garden with multiple rivers flowing through it, now it has become this overly complex thing.
Inb4 what are these strange symbols everywhere?
It's matoran. Basically just the letters from the alphabet replaced with fancier symbols so not everyone looking at it knows what it is. Plus it looks fancy imo.
I call the thing itself "Thran Engine" (don't ask me why) .
It's a big rotating disc floating in black nothingness, held in place by the roots on its sides. The disc's color is a bright blue, the texture like flowing water, the roots are in a very dark grey. Inside the disc an unlimited amount of different islands is floating around, many of them have a big forest and often also a lake on them.
