Sorry its been so long since my last installment of how to build something or what not; getting into college can be a bitch and a half. But Im back and heres the first installment of Demon world terrain.
So what we have here is your average demon summoning gate and a good old chaos icon/statuary(Yes if you go to gamesworkshop you can see who the pros make theirs, this is my take on it). Now I was quick to build this and the pictures showing it step by step didnt come out so Im not going to include them, instead Ill explain whats going on and from this point on Ill take better pictures.
Chaos Summoning Circle 
The gate was made by taking a long piece of foam and carfully sketching out the step pattern. Use a model with a large base for referance on how long to make each step and how high each one should be. It takes some time but once they are cut out it looks really cool. The platform should also be made out of foam but notch the bottom so that the stair piece can fit right into it, makes it easier to build and more stable. The top of the platform should be placed on a pillair of foam blocks that are carved to look unnatural, remember its from a choas realm. On the side of the staircase take a knife and carve out cracks and fissures to represent the powers of the warp ripping apart time and space; once these are painted it will look awesome to and which Ill show you in a later post. To bring the fissures onto the base use wood putty to create uprasied area that look similar to those on the foam.
The demon and terminator lord are to show just how this could be used in a game and for size referance. Yes those guardsmen charging up tje stairs are going to get PWNED.
The top of the platform is very important. Do what ever you want to here to make it fit your tables theme or what ever chaos power you want. To do this I grabbed my bitz box and hot glued some chaos spikes and chain all around the edges of the platform. Then I took a small block of foam and cut it out to look like a pedistal where you could place a book. In front of the pedistal is where the summoning circle will be painted on latter. Take a demon model and trace its base to see how big the circle should be. Try and figure out what you want to paint on the circle now and trace it onto the cirlce. Im using the universal chaos symbol though the marks on the chaos gods would also be good.
Chaos Idol
This one is a little easier then the large under taking of the summoning circle. Carve up a simple pilliar of rock from foam and glue in to a base. After that take a square of foam and cut it down to a square that could fit on top of the pilliar. Take this square and copy one of the chaos symbols onto the block. The easiest is Khorne, so that what I did for my first piece. Carefully carve out the symbol and then glue it onto of the pillar.
The figure is for size referance, yeah its just that big!!!
Thats all for now, next time Ill cover painting and finshing the terrian. Again sorry for the little amount of details, the painting and finishing article will inclue more.;Y
