So I did some research and created a few sketches (albeit terrible) and came up with the idea of doing a dark lord who is a disembodied spirit who possess someone and then tries to rebuild his body from areas of great suffering so I picked a WW1 era battlefield. I was inspired by necromorphs, hellraiser, the evil within and WW1, and I became a little obsessive over the Drycha from Gameworkshop so I used that shape as a base.
