I am trying to make a game and am in need of ideas

[Emotional Learner]

I want to try to make a mod of a game called titan quest. I am planning it to be on the planet Roshar. I will be adding Surgebinding and then creating the world. I was planning the story timeline to start at the end of book two but it might be hard because he hasn't finished the series yet and I don't want to wait that long. So maybe I could start a few hundred years earlier. I also don't know the limits of how much I can modify about the game.   If anyone has ideas or tips it would be much appreciated.
