I want to build the two towers, Sarumans (height 200 blocks) and Saurons (height 800 blocks). For the one of Sauron - I would like to use black cobble - and Sarumans shall be normal cobble. Anyone interested in building with me the towers, help is very welcome.
The location for the smaller tower can be seen in the screenshot. For the real huge one, I'm searching a good, realist place in a mountain range, where a volcano is close.
200 blocks is really huge!
