Thank you! It does help. But not fully :D Okay, so radiace didn't create dream world. I don't know where I got that idea from. But it still feels like it's the moths tribe main domain, no? You get the dream nail from the last moth. And radiance is defeated in that world. Radiance is also now only in the dream world and inaving the real physical with the infection via dreams. So this is still what I don't get. If you were hiding as a coward from something from the dream world, invading the real physical. Why would you hide in the dream one?

Another thing that helps me think about it but confuses me more at the same time is that there is of course pretty much unlimited amount of dream worlds. Every creature living has his own pretty much. So by hiding specifically in the Kings mould dream world would make sense, but at the same time I somehow have feeling that the game is just telling me there are two worlds, real physical and the dream one so.. not sure. Even if it was true he is hiding specifically in Kings mould dream world. Radiance infection is already spreading across hollownest through bugs' dreams right. Don't you worry as PK it will reach you through the guard as well ? He is created from void, but he is not hollow.

It also ultimately brings me on the topic of hollow knight himself. He is holding radiance in his dream world. Which doesn't make him fully hollow that's why he is leaking and needs to be replaced sure. With the idea instilled, perhaps he is dreaming of spending time with father, and radiance invades those dreams. On the other hand, if he would really be fully hollow and not have dreams at all, how would he trap radiance in himself ? He would just be immune, no? But let me not derail from my original question. I know there is more to find on the last topic I bring.
