Arial flail quest in ruins of Delar-tol doesn't show in quests

nod arial You nod at an arial guard. With a grin, an arial guard assumes her battle stance. The sparring session is long and bruising, and she is certainly no guildmaster. However, when she finally lowers her flails and stops, you have learned much. (Your flail skill has improved by 2%.) (You also receive 500 experience points.) I did this quest and nothing shows in my quest list?
