After playing Shadowkeep and all the information about the Darkness slowly coming to light (no pun intended), I really wanted to create a Ghost that was the Pyramid itself. I also incorporated the main entrance to the Pyramid as the frame for the Ghost core.
It was modelled in Maya, textured in Substance Painter and rendered in Marmoset.
