   Summary

   Separated from his brother, Luigi has to survive and fend for himself in The Darklands-- doing whatever it takes, with some help with a ghost dog and some intimidation.

   A slow burn, featuring twin brother angst, sexual frustration across the board and a very intrigued Lord Bowser who is not terribly keen on someone claiming to be 'the Baddest ass in his Kingdom' or how everyone seems to genuinely be afraid of him.
   He's gonna get to the bottom of this and show this little ornery green-bean who's REALLY the boss.

   (It's Luigi, Luigi's the boss.)
