A Hidden Threat

You talk to Shaurom in the Sunspear Great Hall and he tells you that he has a problem which he asks you to investigate.

Objectives

 * Follow Elonbel as he patrols the western riverbank.
 * Now that Elonbel's true allegiance has been revealed, deal with him and his cohorts accordingly.
 * See Shaurom for your reward.

Reward

 * 500 Experience
 * 50 gold
 * 5 Sunspear Promotion Points

Walkthrough
Go and find Elonbel outside of the Sunspear Great Hall, he should be down by the river. Then just go to the mapmarkers shown by the map and you'll come to a camp just outside of the Astralarium with a corsair commandant. He's level 4 and not too hard.

The corsair commandant and Elonbel start talking and when the commandant says "Did you hear that? Curse you Elonbel you were followed! To battle brothers!", five corsair spotters should appear. They are level 0 so one hit should kill them. You can choose to leave them and they will start fighting. Elonbel is level 15 so he will kill them. That just leaves Elonbel. He's not too hard and he only uses healing signet so you can wear him down. Then you go and collect your reward from Shaurom.

If the quest Quality Steel is active, Castellan Puuba (who is also level 15) will accompany you and make the killing of Elonbel a great deal easier. He will lose interest after he completes his 10 kills, so be sure he still has a few to go when the battle with Elonbel and the corsairs commences.

Initial dialogue
"Well met, Friends. You've no doubt heard of the corsair raids? Ah, of course you have. I'm sure you've seen your share of corsair action. We've had our own troubles recently, all coming from across the river to the west.
 * Shaurom

''I've placed a sentry, Elonbel, in that area, but the raiders seem to be getting past him. Could you follow Elonbel on his next patrol along the river and see what he does? But, I warn you, if my suspicious are correct, he may be in league with the corsairs. Make yourselves ready for anything."''

Intermediate dialogue

 * Corsair Commandant: ''"It's about time you showed up. I thought maybe you'd betrayed us. Of course, if you had....
 * Elonbel: ''"Save your threats. I have the information you wanted...and I expect to be paid. Now, the main Sunspear patrols are still positioned along the east bank of the river....
 * Corsair Commandant: "Did you hear that? Curse you Elonbel, you were followed! To battle brothers!"

Reward dialogue

 * Shaurom
 * "You have confirmed my suspicions friend. Such a pity, but I have long felt there was more to Elonbel then met the eye. By dealing with him and his corsair allies you have done us all a great service. But i still have concerns ther may be other corsairs within our ranks. I fear Elonbel may not have been working alone. We shall have to be double vigilant. Thank you for your courage, and may the sun guide you."
