Veil (NPC)

Jungles of Khyber
After you finally reach her by the last room in the quest, she will say:
 * Veil: First, my failure in the Vault of Night... and then the Inevitable chases me out of Stormreach... and now you, a mere, have slain my minions with contemptuous ease.
 * Veil: Were it another time in my life, I would punish you. But I am not the vampire I once was—yes, I am a vampire, did you not know? That is why the Inevitable is after me. It seeks to destroy all who cheat death.
 * Veil: So, will you kill me now, or am I to wait for my death at the Inevitable's hands?
 * You: I'm not here to kill you. Your friend, Marek Malcanus, sent me to help you.
 * Veil: Friend? I did not think that my friends would send help... I had forgotten what a powerful resource the right friends could be. How foolish of me!
 * Veil: I can see now that it was a mistake for me to leave the Laughing Knives. Were they here now, the Inevitable would be but a paltry distraction.
 * Veil: Very well. If you defeat the Inevitable here, I shall return with you to Stormreach and rejoin the Laughing Knives.
 * Veil: This circle will protect me while you face the Inevitable. If you fail, it will not last long....

After you defeat the Marut, she will thank you:
 * Veil: It seems you have rewritten my destiny. Come, let us return to Stormreach.

The Vault of Night
Veil is found guarding the west entrance to the Accounting room. If you talk to her, she will say:
 * Veil: I do not often share my weapons, but I owe you much,.
 * Veil: I offer you a quiver of arrows that will slay your enemies with ease. But aim well—the mage who crafted these missiles for me is long dead; when my last Avengers are gone, they are gone forever.
 * You: I shall wield Veil's Avengers in this fight.
 * Veil: They're yours for the taking.
 * Veil: However, the Laughing Knives only brought enough equipment for each member of your party to choose a single boon.
 * Veil: Are you sure you want my arrows, or would you speak to the other Knives before making this choice?
 * You: I'm certain. Give me the arrows. (Receive 100 Veil's Avengers)
 * Veil: May these arrows drink deep of your enemies' blood.
 * You: I shall to speak to the others first. (Walk away)

After you already acquired an item from one of the members of the Laughing Knives, she will say:
 * Veil: I can spare nothing else. Good hunting to you.
