Glasya invited Athanatos to Malbolge via a temporary portal located in Skyhammer. There, she revealed that she had actually been "The Shadow" the entire time, and had been communicating with Athanatos in the hopes that she would assist Glasya in freeing herself and her fellows from Skyhammer's imprisonment. Athanatos accepted, with the understanding that if she succeeded, there would be a special place in Hell for her to thrive within.[1]
After the utterance of the Second Wish, the Risen saw Glasya in a vision. Making the Hell Seal permanent without the use of Arcane Bridges freed Glasya from her bonds, allowing her to once again move freely around Hell. She was last seen walking toward a newly-appeared Tarrasque.[2]
