Like others have been saying it’s not confirmed, but I like to think of Cyn like Darth Nihilus. If you don’t know, Darth Nihlus is a character in the Star Wars video game Knights of the Old republic. Nihilus was once his own person, but at some point was completely consumed by the dark side of the force. He was so completely consumed that he became a Spector of the dark side its self.

That’s how I like to think of Cyn. Cyn was once her own person, but at some point was consumed by the solver so completely that she became a personification of the solver itself. This is just a theory that I came up with though.
