SOT could keep a tally of every time you shot first at pirate. Or sunk a unmanned ship ect.
What would happen is after you hit a pirate legend that at night your true colors show. kinds like old fable was..
Do good things get a nice look and blue aura and opposite is true 2. Be a very evil and get a red glow at night/look more evil scars black/red aura.
Would be a throw back to fable 1 also.
Just a 2 second thought I had it is far from fleshed out
