Overview

 * Reward: 250
 * Reputation Gain: N/A

Walkthrough
After finishing the quest Diplomatic Immunity and saving Malborn you'll find Malborn hiding in the New Gnisis Cornerclub in Windhelm. Talk to him and he will tell you that he is trying to flee to Morrowind but can't because he's afraid of the Khajiit who he thinks is a Thalmor agent that wants him dead. After you agree to help him, you need to go to the Khajiit caravan camp. Once you arrive, the marker will disappear, and you'll need to find out who is the assassin.

At this point, the player has two options to find out who the assassin is:


 * 1) If you pickpocket J'datharr, you will find J'datharr's Note. This will prove J'datharr as the Thalmor assassin ordered to kill Malborn.


 * 1) If Ri'saad is present, a dialogue option appears where you may ask him about a Thalmor assassin. He will point out that J'datharr is not one of their caravan and is the assassin. If you then talk to J'datharr, he will become hostile and attack you. However, should Ri'saad not be present for whatever reason the Dragonborn can go ahead and kill J'datharr without gaining a bounty.

After you kill him, head back to Malborn and he will thank you and give you 250 gold.

Interesting Notes
If the player follows Malborn after receiving the reward, he will follow the path east, occasionally engaging the Frost Trolls and Ice Wraiths along the way. Should he survive these ordeals, he eventually reaches Refugee's Rest, where he disappears, for good.

Bugs

 * It is possible that even after completing this quest for Malborn he will still have the dialogue option to start the quest, note that this does not mean you can redo the quest he simply just explains the situation he is in every time you select the option.
 * If you fast travel outside of Windhelm to the assassin, he and the caravan may disappear.
