{Aht Urhgan Whitegate }Talk to Cacaroon at (G-11) for a cutscene. The right cutscene opens with "Cacaroon got cheap info, ya?"
If you get a cutscene related to Two Horn the Savage, go back and talk to Naja Salaheem, then return to Cacaroon again.
If you are on the part of the quest Rat Race where you must obtain information from Cacaroon, he will not give you the cutscene for this mission until you have completed Rat Race.
He may mention something about Mamook being very spooky. If he does, just talk to him again.
