Since I only have this stupid bike that I can't use, I asked Greva if she could be my personal assistant and drive me around on my own personal hovercar. That you will produce for me. Now. What if I say please?
Guess what? Greva said yes! Oh, and thank you for the hovercar. Please accept this little gift as a sign of my gratitude.
You can get any of these quests apart from the ones you have already completed.
