Hitting it where it Hurts
Viidu has learned that Skavak plans to sell your blaster shipment to a separatist leader named Dareg in the hidden separatists' stronghold. You need to get there before the trade so you can recover your ship and cargo. Go to the rendezvous point inside the stronghold to stop Skavak from selling your cargo.
Your first task is to go to Skavak's Rendezvous point. From Oradam Village, head southwest past the Volcano Camp and enter the Separatist Stronghold. Fight your way to the ramp which takes you to level two of the Stronghold, and then locate on the map the exit to level three and make your way over there. Open the map again to locate Skavak's Rendezvous point in this level, and head there.
When entering the Rendezvous point, kill a separatist arm dealer to start a bonus mission, "Stop the Weapons Trade". Kill a total of 5 separatist arm dealers to complete this bonus mission.
Speak with Separatist Leader Dareg, tell him Skavak stole your freighter and you want it back. Dareg tells you that you are guilty of crimes against the oppressed people of Ord Mantell, and that the sentence is death. Defeat him and his group, then talk to Morant who may have information about Skavak. Morant tells you that Skavak is long gone, he left hours ago, after stealing some rusty antique droid from Dareg. Mortant continues to tell you that Skavak has a girl at Fort Garnik named Syreena. It was Syreena who warned them you were coming. If you want to find out where Skavak went, Syreena's the one who knows.
Corso Riggs will want to execute Morant, since separatists killed his family. When you get the options:
Stop!
This feels wrong
Orders are orders
Choose the third one for 100 dark points and 15 affection from Corso.
Your mission log has been updated:
Skavak is gone, but you discovered that Syreena has been working for Skavak the entire time. Return to Rendia Freight inside Fort Garnik and confront Syreena about her betrayal.
Your task now is to find Syreena. Quick Travel to Fort Garnik and enter the Rendia Freight Building. You walk on Syreena as she is talking to Skavak through the holocommunicator. Viidu is dead by her hands. She asks Skavak to come get her, but he ditches her. She tells you that Skavak used her like he did everyone else, that man can charm the armor off a Mandalorian. Rogun the Butcher's bounty hunters are on their way right now, we don't want to be here when they arrive. Skavak took your ship and guns to Coruscant. If you go now, he won't know you're coming for him.
The separatists are retreating from this island thanks to you, and the Republic just reopened the shuttle port. She will give you a shuttle pass to Coruscant if you let her disappear.
The options are:
I Guess we do (LIGHT)
I want more (NEUTRAL)
No need. [Kill Her] (DARK)
If you choose the third option, you get 100 dark points and you lose affection points with Corso, who accuses you of being cold-blooded. Where he comes from, real men don't shoot ladies.
This competes the final mission on Ord Mantell, "Hitting it where it Hurts", and starts the next mission, "Chasing Skavak", which takes you to Coruscant, the capital of the Republic.
