You could sneak off and have Faendal waiting a distance away and buy archery levels and take money back. Don't bring Faendal because he would want to kill him. Go above embershard mine and drop onto the outcropping. Note an altmer can use fury on Rolof or the other guy and level illusion, block, light or heavy armor, one handed, and restoration. Disregard, we're going to work on one handed, sneak and destruction.
Grab the key from the dead woman captain before he does. Put the name of the skill into the search bar there for the others.
