Igor and Nonoa walked and talked, and unwittingly, Nonoa had already informed Igor about the general situation of this Border Realm.
It was only at this point that Igor realized that this place was a convergence of worlds.
This place is called the Border Realm because it is where worlds converge. As for how these worlds converge, Nonoa didn't elaborate, but Igor speculated that this convergence has something to do with the Spirit World.
Of course, Igor still can't determine exactly how many worlds there are. He only knows about his world and the Spirit World. Whether there are other worlds requires further exploration, and Igor is willing to try if the opportunity arises. But those are matters for the future. For now, Igor's focus is to understand this Border Realm and then find Tobin, to send him back.
Through Nonoa, Igor gradually understood the survival rules of this Border Realm. Here, the strong reign supreme; as long as you have formidable power, you can move unhindered.
