K so I'm working out a story idea with a friend and I'm trying to think on this character I have forming in my mind. they would be nice and "helpful" and everything, but the thing is she is the mastermind behind the evil plan going on by the presented antagonist, who she is in control of. The character has created a dark force to track down these items which have a lot of power the hero gets summoned to the world to try and stop them. it's a pretty simple plot with a few personal twists and minor mods that I hope will refresh the idea some. so, I want the character to show up and be helpful and everything but I don't want them to seem too helpful or be a total guide or anything. At the same time I don't want it to be like "Who is she and why isn't the story over yet?
