No. They are part of the "Citadel" project. There is a link by the Add-Ons to help you explore those features. It is a really huge openlock infinite design castle/castle ruins product that also include the massive walls, towers, and gatehouse you see on the image. They are in the image to make it more compelling, essentially I am following the "Rule of Three's" and also using the size of the wall and its diagonal angle to redirect the viewers eyes back to The Tower and Siege Tower. :) Happy art lesson day!
