A Murder of Crows

A Murder of Crows is a quest in Act 3 of Dragon Age II wherein a man claiming to be an Antivan noble tells you that he is pursuing a dangerous assassin. He says he has been attempting to bring the criminal to justice but that his quest has become personal since the man has killed several of his subordinates. When asked why he has come to you for help, he says that the assassin is an elf and is blending in with the nearby Dalish tribe so he needs someone more familiar with the Dalish to track him down.

Upon ascending the Sundermount and fighting a Varterral you come across the assassin -- it's Zevran! You can choose to take him in or let him go; in the process, you can flirt with him. If you let him go, he runs off; there should be a new camp on the marshes map. Go there, the man who "hired" you attacks you and Zevran shows back up to help you fight him off.

Helping Zevan will cause him to return the favour by assisting in your battle against Meredith.

Notable Items/Rewards
Bring a rogue since there are chests and traps you need him to unlock/disarm.

If you loot the cave, you can get Boiled Leather Plates - Upgrade for Isabela, Righteous Rain, a bow, and Ring of the Shadow Hunter.

After defeating Nuncio, you can loot the camp for Proving Battle Tunic. If you choose to let Zevran live, he will also give you Finesse.

Note
If you have Isabela in your group and allow Zevran to go, she asks him for sex before he takes off. Zevran will agree and you are given the option to join them for a threesome and Zevran will comment "The more the merrier". If Aveline is in your party, she will say that she just threw up in her mouth a little. Isabela's "needs" might be based on the relationship/romance status with Hawke, or if the player flirted with Zevran in the dialogue.

Bugs/Glitches
Due to unknown reasons, introduction dialogues might trigger twice, before letting Zevran go and after dealing with the Crows. Also, quest might stay active in the journal even though it is finished.

This mission will occur even though you import a saved game from Dragon Age: Origins where you kill him.
