The camp is quite short and easy to navigate, just stick to the main path ignoring all side rooms. At the end of the dungeon you will find Baron Entemarre next to his throne, kill him and take his severed head.
Hashina tells you, "Queen Elysa has sent me here to establish a formal relationship with the good people of Silyun, who have rebelled against Varicci's tyranny. In order to aid them in their fight, I would ask you to journey into the Direlands near Ayan Baqur. The Viamontians have built a fortress at 62.7S, 82.5W. Bring me the head of Baron Entemarre, the garrison commander. The people of Silyun seek vengeance upon Entemarre for his brutal tactics in the earlier rebellion."
Hashina tells you, "Have you found Baron Entemarre at his encampment in the Direlands yet?"
You give Hashina Entemarre's Head.
Hashina tells you, "Yes, at last... This wretch Entemarre was responsible for great suffering among the people of Silyun. You must realize that there can be no official acknowledgement of your deed. However, I can reward you through my own resources..."
You've earned 15,000,000 experience.
Hashina gives you Whispering Blade Gloves.
Hashina tells you, "You have already helped me by slaying Baron Entemarre. There is nothing else I would ask of you now, but you have my continued gratitude."
