That would be Ein Sof, or "the incomprehensible". Before God descended from void into form as Adam Kadmah, elohim was chaos. This is where hebrew eschatology, kabbalah and gnosticism find crossover.
The incomprehensible form of chaos in gnosticism becomes yabdaloeth when the principle of wisdom (sophia) attempts to understand chaos, applying reason to infinity.
Adam Kadmah is his descended form, elohim as the First Man. This may be considered a form of prometheus/morning star/lucifer figure, the idea of a descension of god-as-man in the flesh.
Keter would be the point of dissolution, when chaos distilled into what I will call Christform, stemming from my more gnostic-leaning lens.
