Going through my 3rd journey, and still a bit remains in The Dark Tower on this one, but had a thought about the glamour guys at La Casse Roi Russe. They said something to suggest Crimson King is an aspect of Gan, and it’s suggested that Stephen King is channeling Gan. Roland and King are connected as twim, but I thought what if Roland, CK and SK represented the ego, id and superego of Gan / that they’re all connected.
Roland and CK both have marks of Eld to gain access to the Tower. I don’t know if this means anything, but seemed to click as I was reading.
