The Arm that Holds the Saber (Jedi Knight, Tython)
Talk to Aven, at the base of the entrance to the Jedi Temple, to begin this mission. This is a level 2 Jedi Knight Quest.
Aven: Peace onto you, friend. I bear word from the masters of the temple. Will you take a moment and hear my message?
You can tell him:
Of course
I have an urgent mission
You talk stupid
Choose the first option. Aven tells you that you do him great honor. Your present mission is all important, but the Masters want to make sure you do not miss what the temple has to offer. When you have time, see Master Muheeda. He will guide you in the other skills of the Jedi.
Open the mission log:
The Arm that Holds the Saber
Aven, a fellow Jedi, has recommended you speak with Master Muheeda to improve your skills. Speak with Master Muheeda on the upper level of the Jedi Temple.
Enter the Jedi Temple and climb the spiral platform to the second level of the temple. Open your map and locate the marker for Master Muheeda, in one of the big rooms. Speak to him to complete this quest. Master Muheeda is the Jedi Knight trainer and you can come back whenever you level up to learn new Jedi Knight skills and improve existing Jedi Knight powers.
Wisdom of Elders (Jedi Consular, Tython)
Talk to Hallen near the Jedi Temple to start the mission. This is a level 3 Jedi Consular class mission.
Hallen: Hey, Padawan! You must be the one Master Yuon mentioned. Must be! If we weren't Jedi I would say I could tell because you are as cute as described. But we are Jedi, so I will say nothing of the sort. Sorry, babbling. Master Yuon said to remind you that she says a Jedi needs to learn martial skills and said that I should say you should.
Ask her where to go. She tells you to go see Master Wettle in the temple. Doesn't look like much, but he'll show you stuff you wouldn't believe. Good luck - may the Force be with you!
Enter the temple, go to level 2, then talk to Master Wettle who is standing inside one of the big rooms. Master Wettle is the Jedi Consular Skill Trainer and as such will teach you new skills as you level up.
