We'll try to keep the technical jargon to a minimum (not that we'd understand it ourselves). Basically, when you create an environment in Titan Quest, you make a "World File." Your sagas can take span as many of these world files as you wish, and you can link them together as you see fit. Out of the box, as it were, a world file is just a large, featureless terrain. Your first objective, then, will be to carve some character into it. Literally. You use the "plateau tool" to do this. Think of it as a paintbrush that you use to raise chunks of your land, or create recesses into it. You can adjust the size of the brush, as well as the dimensions that it will effect, and using it, the designer conducting the demo was able to create small valley in a matter of seconds. Then, he used a smoothing tool to give the terrain he'd just created a more organic feel.​
