Objectives: Confront Freyyr and find the Star Map
Beware the viper kinraths here; they have a poison attack that can slowly sap your party's health if you don't stay on top of their vitality totals. If you gave Jolee the knight valor Force power, use it before entering battle to protect your entire party from the poison.
Speak to the Wookiee fighting the Mandalorians and heal him to get the Hidden Hunters side quest, then head south to find Freyyr in a small cul-de-sac. You'll need to fight him before he'll calm down enough to speak with you; any Force powers that are capable of stunning will come in handy here.
Once Freyyr calms down, you can either proceed with the assassination that Chuundar requested of you, or attempt to help him in his quest to be reinstated as the chieftain of the Wookiee tribe. He'll ask you to find the blade of the mighty Bacca, an ancient Wookiee tribal leader, which was lost in the hide of a ferocious beast elsewhere in the Shadowlands. You'll need to find some bait before the monster will reveal itself to you.
Explore the area, killing the viper kinraths and pick one up into your inventory. Take its body and head to the ritual marker in the southeastern corner of the map, then suspend the body of one of the kinraths from the dangling vine there, making sure that your party is healed up with full Force points before you do so.
A tarentatek will appear behind your party; this massive beast, as you may have learned on Dantooine, preys on Jedi, among other things, and has a limited ability to use the Force, in this case restricted to the Force push power. Your own Force powers won't be very helpful against it, but you can still utilize defensive measures like knight valor or Force shield. The tarentatek has a lot of health, but luckily doesn't deal much damage; you shouldn't have a very difficult time defeating it. Once it dies, you'll obtain the blade to Bacca's Sword; check the body further to obtain the journal of one of the three Jedi who were tasked with killing these beasts.
For now, though, bring the blade back to Freyyr, assuming you didn't kill him earlier. He'll go topside to attempt to marshal some troops for a confrontation with Chuundar. Travel all the way back to the elevator, where Gorwooken and a couple of friends will attack you. Unfortunately, there's no way to avoid this fight, so dispatch them and head topside.
Once you arrive back on the Great Walkway, you'll encounter another Wookiee who'll warp you directly to Chuundar's hut. If you're a Light Jedi, you should attempt to talk Zaalbar into attempting to compromise between Chuundar and Freyyr. It won't matter, since Chuundar will start a ruckus anyway, but you'll get a positive alignment adjustment. If you're going for Dark side points, double cross Freyyr and get Zaalbar to side with Chuundar.
