New Terrain has been spotted in the General's Handbook that is surely to be released soon. Above is the image that you need to see... which is out of the General's Handbook.

I spotted this while going through the book this morning. There is a wall/mountain of giant skulls on the left side of the board. The tops at parts of it look like fortifications. I don't see this on the website or posted anywhere so I thought I would share.
