It was a long stairwell and there was a lack of torches on the walls after Sionn had climbed it down for a while. Eventually she would have to cotinue in utter darkness, or turn around and go back. Then finally, when she was starting to risk falling down and break her neck or something, there was another torch. When Sionn was directly beneath it, she could see that her belly had grown even more. It was big and round and smooth....and something was stirring within.
