Can someone explain what is the root, because I still don't understand the world build

so the root is kinda like the originator(?)of the world, and it can link dimensions togethor that becomes a dungeon, and root children are like monster or higher beings , but in short the root is bsically like god

it's the source of everything.

So basically Jio is the root and the goddess of the godhood? Ive been reading the root and the garden many times since I can't seem to understand that much just need a confirmation

It's a bit of a spoiler but yeah basically. hes the root and hes now also the new sun god (different from the sun goddess from the solar cult fyi)
