Ok, so after I gave Sara's pendant to the Master Smith, she disappeared from Northwest Saronia. I have all my characters lvl. 99 in the Onion Knight job, and now I'm just trying to find her so that I can get my reward. I've looked in all ten possible locations where she randomly shows up. I've even exited, and re-entered a certain location time and time again, yet she hasn't appeared. Am I doing something wrong?

IIRC, you also need to do the "Find Orichulam!" Mognet sidequest

I haven't done that yet. I think I need to receive a letter or two more, and I'll be able to complete that quest.

Well I finally found her in Falgarab. My entire party has mastered the Onion Knight job, and I'm trying to get each of them an Onion Sword. So far, she has only given me one. Do I not get a weapon or armor for each character, or is it only one per mastered job?

That Im not sure of. It makes sense to be able to get 4 swords. How many have you played the game?
