We’ve covered the main quest-line with respect to the Dawnguard faction already in a guide here. In this guide we’ll be going over the quests that you would have to complete if you sided with the vampires, hence becoming a Vampire Lord.
Do note that many of the quests are share similar objectives and locations, irrespective of which side you are on. For details of such quests, please refer to our Dawnguard Quests Guide.
The first quest, irrespective of who you plan to side with, is the Dawnguard Quest itself, which is mandatory to initiate the DLC’s main quest-line. If you are above level 10, you will begin hearing rumors of the Dawnguard faction.
Travel to Riften and talk to the guard at the gate. He will give you brief information about Dawnguard, and will eventually point you to Fort Dawnguard.
You’ll have to head into a small cave that leads to Dayspring Canyon. You’ll run into another fellow looking forward to going to Fort Dawnguard, Agmaer. Follow the road and you’ll eventually reach Fort Dawnguard.
Isran, the leader of the faction will be there, and you can talk to him to initiate the next quest, Awakening.
The Awakening quest is all about exploring the Dimhollow Crypt. This is a fairly easy dungeon – refer to our Dawnguard Quest Guide for the details of enemies and the naturally occurring items you can find here.
Towards the end of the dungeon, you will come across a puzzle. This is the iconic puzzle of the dungeon, and the solution to it can be found here.
Once you have completed the puzzle, you will find a Mysterious Woman, whose name is revealed to be Serana. Talk to her and try to find out what is going on.
In this quest you will be escorting Serana back to her home, Castle Volkihar. For more details regarding this quest, refer to our Dawnguard Quest Guide.
Once you have made your way to the castle, you will eventually end up meeting Harkon, Serana’s father and the powerful leader of the Volkihar Vampires. Harkon will offer you his blood and a reward, which will give you the ability to turn into a vampire.
If you accept, you will gain the ability, and ultimately follow the Vampire Lord quest-line. If you decline, then your inevitable place is with the Dawnguard, in which case you should be reading our other guide.
The Bloodstone Chalice:
This quest is only available to you if you accept Harkon’s gift of becoming a Vampire Lord. Once you have done so, you must speak to Garan Marethi, who is present inside the castle. Follow him, and he will hand you the Bloodstone Chalice.
You have to fill the chalice up with the water of Redwater Spring, which is located in the southeastern portion of the map. You’ll actually have to make your way through the Redwater den in order to get to it. Head down the trapdoor into the den. The doorman will have some words of warning to tell you before letting you in.
You’ll have to pick the Adept-level lock here to head further, which honestly shouldn’t be difficult for a mid-to-high level character. Once you do that, everyone will turn hostile here, meaning there’ll be plenty of fighting to do.
Make your way to the upper floor of the main cavern and activate the lever to lower the bridge, and cross it. Now, search for a chain lever that will allow you to progress deeper into the place.
You will eventually reach an area with pressure-sensitive tiles on the floor, which you should avoid at all costs, as they tend to spring spikes from the wall.
Continue through the iron door to find yourself fighting a few enemies, one in particular with the name Venarus Vulpin. Kill this vampire, and loot his body for the Redwater Spring key.
Fill the chalice with the glowing red liquid. On your way back you will encounter a pair of enemies, two elites that you should deal with individually if you have trouble. Perhaps the Vampire Lord formation would be of good use if you haven’t tried it yet.
Once they are down, put some of their blood in the chalice and return to Castle Volkihar and speak with Garan and Harkon to complete the quest.
The quest Prophet is shared both by the Dawnguard faction and the Vampire Lord. Your common initial objective is to find the whereabouts of a Moth Priest that has arrived in Skyrim. To do so, refer to our Dawnguard Quest Guide, which details how to find the location of the priest.
