It is. Also the sage mentioned here >>529498848 is the person who would become the Godhand Void in an Eclipse. That's why Gaiseric's empire fell, and the Skull Knight seemed to know Void the most out of all the current Godhand.

Shortly before Miura's passing one of the most recently released chapters showed the old Godhand, back when Void first joined.
