I think trapping Niran in a hellish limbo is promising. I personally would be entertained by an exploration of this "timeless place between realities". You could do this symbolically or as a kind of magical journey.

I completely agree @agmoore thank you for the feedback. I had it in the back of my mind for the beginning to the next story being a sort of mishmash of symbolic imagery from Niran's past to fill out his character a little, kind of like Mr Xioin is fucking with him psychically before moving on to the next scene (I don't want to post any spoilers).
