After a cople of unsatisfying versions, and restarting all over again, and after building 3 versions of Orthanc from scrach, I've mannaged to creat a satisfuing version of Orthanc & Isengard. From this point I started working on Orthanc's Interior, Isengard's inner circle area, and a simple quest to go along with it. Then I desided, wy not give a shot at trying to creat the surounding scenery? So I started learning Tolkien's maps and building in my head the topographic look of the vecinity of Isengard. Then I Expanded the, already very big, Islend on wich my Isengard was built, and starting to rais Mountains (corisponding to the Misty Mountains).
Finally, to finish the look & feel of the mod, I started experimenting with texture coloring, furnituring, and a most excrutiating learning of usage of dialogue and scripting.

After almost 2 months and over 300 hours of work, I've done some "Finish" work on the mod, and the extremely informative Readme file,and Here It Is!
