I was on a green giant quest. Suddenly, Nameless appeared. Nameless asked, “Tell me if I give you a chance to change my previous decision. Will you take that opportunity?”
Which one should I choose to make the story better?
The game is still in development so no one can say what Nameless actually wants or is going to make us do if we refuse or accept to serve him. So really choose what you feel is the best answer but until we get more updates expanding the story to actually see differences between the two options no one can say how it will play out.
