I thought this quest was of significance since the Black Mage does appear in it. I'm not sure if this matters but I picked Light for first job.
Started recording it after I accepted the quest and warped. I was at 0% but I think warping with the "Aurora Prism" gave me 5 mil EXP.
Don't mind the ending haha, I was like O______O how much EXP did this quest give?!?!, gave me 1 full level(130->131 worth of EXP) though.
