The fight here is one of the most fun in the game, since it's essentially just 12 characters thrown into a room and told to kill each other. You'll have Freyyr (or Chuundar) and Zaalbar fighting alongside your party, though you won't be able to control Zaalbar, while Chuundar has four Wookiee guards and a couple of Czerka goons by his side. As soon as the battle begins, you'll want to keep it paused and throw down some Force powers to knock the Wookiees on their collective ass, if indeed you have been investing in the ass-knocking powers (again, Force whirlwind is your friend). The battle, surprisingly enough, is not all that difficult. Sure, Chuundar (or Freyyr) can hold his own, but the other Wookiees don't deal very much damage, and the Czerka soldiers might as well be wall decorations. Once all of the enemies are dead, you'll obtain Bacca's Blade, which is arguably the best non-lightsaber melee weapon in the game.
You'll have to fight through a royal rumble to solve this Wookiee leadership dispute.
After that, or before that, depending on how adventurous you were, you can find the Star Map in the southwestern corner of the Lower Shadowlands. It's guarded by a computer holosimulation, set up by Malak and Revan to protect the Star Map from anyone but themselves. You should interrogate the computer for all the information you can get, if only so you have more of the backstory. Once you're ready to begin, start to pester it about the Star Map, and it'll start posing hypothetical questions.
You have two basic choices here. Firstly, you can put yourself in Revan's shoes, and answer as he would, i.e. thinking only of your own interests and seeking to maximize your own protection while disregarding that of others. So, you respond:
| 1. | I would accuse Zaalbar to be safe. |
| 2. | My forces attack in ten days. |
| 3. | The death of those people would cause my people to fight. |
| 4. | I let the attack happen. |
Even though you're responding to hypotheticals, you will take a significant Dark side shift from responding this way. If you care to avoid that outcome, answer the questions honorably, and the computer will eventually sic two defense droids on you. These things have shielding that prevents most damage, so you'll have to either ionize them (use any grenades you have) or use stun droid or disable droid to hopefully allow your teammates a bit of uninterrupted time to drop the shields. Even after their shields fall, the droids have resistances to most forms of attack, so you'll want to stick with the ion guns until they die. As usual, if they're too tough for you, and you're adamant about achieving a Light side result, simply come back after you've achieved a few more levels and try again.
After the droids are destroyed, talk to the computer again and it will allow you access to the Star Map.
