Dialogue
 * "The time when our king may freely roam this world again is surely drawing near. Then it will be like the old times again, the blessed way things once were. Imagine the thrill of being alive when any moment could be your last! Wouldn't life taste that much sweeter? If only those unfortunate peasants could have seen that gift for what it truly was!"
 * "But before the king may walk free again, one of his greatest rivals must leave this world. The name is Qwytzylkak. I had never seen anyone equal our liege when it came to telling jokes... until those two crossed paths. I nearly died that day from laughing too hard. How I managed to survive is still a mystery. But one thing is NOT a mystery: Qwytzylkak must die! There can be no one funnier than our great king. I've heard Qwytzylkak was last spotted in Vehtendi Valley. Go and knock 'im dead."


 * Accept: "This is one punchline I'm ready to deliver."
 * Reject: "I don't think I can handle any more bad jokes."

Reward dialogue
 * "Oh, how I wish I could have seen the look on Qwytzylkak's... well, whatever it has that passes for a face, when he met his terrible end. Surely, great King Thorn must be free now! Strange... nothing really feels that different. But I'm certain our plans went ahead flawlessly! One thing is certain: the barrier has weakened. If this is not the year that we succeed, then by the next... by next year our court will rule again, and this world will once again know true brilliance!"
 * "You have done your part well, and for that you will be rewarded. Now, go! Enjoy your time in our king's presence. Savor the knowledge that this is the future awaiting you!"

Walkthrough
Enter Vehtendi Valley from Yahnur Marketplace, and follow the quest marker to his location. He spawns near a group of Behemoths, but is not very dangerous on his own.

Trivia

 * Qwytzylkak's line of dialogue is a joke, encoded in a cipher. Decoded, the joke is (highlight to read): Why did the Seer chase after the Eidolon? Because time was of the essence!
