New Allegiances

Background
"I've found a new candidate, ripe for Harkon's Gift. I'm sending you to welcome this soul into our family"

Walkthrough
The quest is given to the Dragonborn by asking Vingalmo if he needs any help. He then informs the Dragonborn that there is a person that is deserving of the gift. He instructs the Dragonborn to head to the person's town and use the Vampire's Seduction power on on him. After the power is used, the Dragonborn can feed on the target (when awake). After feeding, report back to Vingalmo for the reward.

Possible targets

 * Cairine in Markarth
 * Valindor in Riften
 * Haran in Winterhold

Rewards

 * Random item with a random enchantment on it
 * Alternately, three Potions of Blood

Trivia

 * After feeding off of the target, he/she says that he/she is not feeling right and must go lay down.
 * After returning to the target, he/she makes a comment to the Dragonborn saying that they have given him/her a great gift.
 * The target says that the Dragonborn may use his/her coffin whenever they feel the need.

Bugs

 * You may be given this mission even if the target is already dead due to various reasons. Such as killing or completing a quest involving the NPC's death.
 * You may be given this mission even if the target has already been turned by you in a previous New Allegiances quest, preventing you from turning them again.
 * Sometimes you are given the same target a second time while doing miscellaneous quests for the vampires at Castle Volkihar. This makes the quest unable to be completed because the target is already a vampire.
 * Sometimes you can get around this by killing the targetand getting "Quest Failed". After doing so, return to the Keep for the next Quest. *
 * Another solution - Save before handing in last quest, hand in and see what mission you got, reload and repeat till you get a new target. Save before handing in last, new quest is chosen when you do so.
 * Cairine may cause the player to become immoblised as if they were still talking to her after biting her.
