[@Bishop]You cannot increase the maximum amount of points you spend on attributes, nor will the story offer more. Think of advantages and disadvantages as a layer that carries more weight than attributes, but is not absolute. 'Increased pain resistance' is like armor in addition to your hit points, if one would severely simplify all of this.

Your character can be haunted by 'something'. You can suggest what it is, but if it doesn't fit into the lore I'll change it so it does. Or, lastly, I'll can create this 'something' for you. I will also control the actions of this 'something' in the story.
