Story wose Nutral IS actually possible as nutral isnt a disqualifying trait for a hero. Nutrality would be supported by the fact that no matter where we are we're outsiders with no national alligence. Even when enlisted in a grand company they courted US to join and we still serve under the "mercenary branch" that all adventurers go to.

So I'd go aa far as to say not only are we incapable of being truely evil, but by acting in Hydaelyn's behalf rather than an individual power means we are, by default adherently, true nutral.
