Start: Pwwoz Pwwa, [449,-1118], Mensix Mining Facility, Mustafar

Part 1: Scene of the crime - Pwwoz’ camp site [-2505,-1232]

Part 2: A flea in a haystack - Combat: A bunch of Lava Fleas (CL65) spawn in the camp, kill them until you get the crystal

Part 3: A decision to be made - Return to Pwwoz; You can choose to either give him back the crystal or keep it

Option A (give):

Part 4: Possessed - Combat: If you choose to give it back you’ll have to fight him, Pwwoz Pwwa (CL83 Elite Jedi); You only get the reward if you defeat him; If you die you can go back and fight him again

Option B (keep):

If you choose to keep it you’ll finish the quest and get the shard, but 2 Hired Thugs (CL70) will spawn and attack you at some point (you don’t have to fight them though)
