I don't understand why DM is even mentioned here, it isn't a thing in a video game. The closest to an actual DM in digital form is ChatGPT, you can actually coerce it to fit your headcanon and react to anything you do. The best thing Larian can do is to make a coherent character with a good explanation of it. Good thing there is an intro for each origin stories, and Durge one couldn't be clearer on what you are getting into.
