The Arm That Holds the Saber/Notes
This quest is only available to Jedi Knights; other classes have their own versions. It is a vector quest designed to direct you to your class trainer, and (if you have not yet done so) provide you with the opportunity to buy any new skills that are available.
Aven is located on the right side of the steps leading into the Temple. Master Muheeda can be found by entering the temple, going up the left ramp, turning left at the top, and taking the first corridor on the right. This will take you to the Temple Library, and Master Muheeda is to the left side of the room. He will not have a quest icon over his head, only the usual Class Trainer symbol. However, there will be a quest icon over his position on the mini-map.
Good luck on all your journeys!
