>>38351954If you mean what the concept means, the spheres just represent different aspects of God's creation. With the one on the top (Crown) being the closest to God, and the bottom one (Kingdom) being the physical world. The others are just random stuff like Beauty or Wisdom. The 22 paths linking them also have some meaning but I forgot what it was.
If you mean what it has to do with Gen 8, just look at the map of Galar and the way the towns/cities are placed. The large rocky wall also matches the "Abyss" separating the three upper spheres from the rest of the tree,
