After completing "Glory of the Dead," return to Jorrvaskr and talk with either Farkas or Vilkas. Instead of offering one of the usual radiant quests, they will ask for help cleansing themselves of their beast blood.
The Dragonborn must have the Glenmoril Witch head(s), (see "Blood's Honor"), in the inventory before accepting a radiant quest, or "Purity" will not be available.
The quest is relatively easy, as the shortcut to the final room is already open and allows for easy access. (Upon entering, while facing the statue, take the door on the right. Follow the tunnel, go down the stairs and continue to the main chamber.) The only enemy in the quest is Farkas's/Vilkas's wolf spirit unless the tomb has not been previously completely cleared by the Dragonborn.
Once the quest is over, Farkas/Vilkas will be cured of their lycanthropy and will offer the usual radiant quests.
If the witch heads are stored somewhere and then retrieved after completing a few radiant quests, "Purity" will not show up immediately when talking to Farkas or Vilkas. The Dragonborn must first complete a radiant quest from each of them, with the witch head(s) in the inventory to make "Purity" available.
When asking for a job from either Vilkas or Farkas, if they have the option, "Is there any work to be done?", they may offer this quest.
It might be a good idea to bring at least one Cure Disease potion to the fight with Farkas'/Vilkas' Wolf Spirits since it is possible to contract Rockjoint from them.
While Kodlak's Wolf Spirit is red, Vilkas' and Farkas' (as well as the Dragonborn's, if they choose to cure themselves) Wolf Spirits are blue.
This section contains bugs related to Purity. Before adding a bug to this list, consider the following:

360 To avoid bugs, first speak to Vilkas. He gives a random quest, then he gives his "Purity" quest (remember to have the head(s) in the inventory). Decline his "Purity" quest. If Farkas does not give any quest after that, take one of Aela's random quests and complete it. This will unblock Farkas's random quest. Do the quest and then complete his "Purity" quest. When that is done, Vilkas will complete his "Purity" quest without a problem.
360 One does not need to speak to Vilkas and decline his "Purity" quest to avoid bugs. Instead, alternate Farkas' quests with Vilkas' throughout the Companions' main questline; one from Farkas after beating Vilkas and being shown to the Dragonborn's room, and one from Vilkas after retrieving Wuuthrad's fragments from Dustman's Cairn. Continue to alternate quests from the brothers in this manner. After curing Kodlak inside Ysgramor's Tomb, find Farkas and get another quest from him. After Farkas gives his "Purity" quest, complete it and this should allow Vilkas' "Purity" quest to be given and completed without problems.
If the Dragonborn arrives at Ysgramor's Tomb before Vilkas, while the quest is already enabled, and cleanses Vilkas without him present, then the option to talk to Vilkas afterward will not be there. The quest will instead count as finished, and Vilkas will cease to give any side quests. Upon returning to Jorrvaskr, Skjor is found to be alive and still refers to the Dragonborn as a "whelp." He also has no side quests available.
PC 360 PS3 After declining Vilkas's "Purity" quest, neither Farkas nor Aela have the option for any side quests in their dialogue ― only the option to "Follow me." When attempting Vilkas's "Purity" quest, he leaves the Dragonborn as soon as they step outside of Jorrvaskr and the quest is moved to the 'Completed' list. Speaking to Vilkas again only offers the "Dragon Seekers" quest. When attempting to recruit a follower, characters will note that the Dragonborn already has someone with them when they do not. This bug is due to the "Purity" quest.
After completing "Purity" with either Farkas or Vilkas, if the Dragonborn immediately talks to the other one, sometimes the quest will show up in the completed quest section, and the altar in Ysgramor's Tomb will not be able to be activated.
This can be solved by loading a save state from before the first "Purity" mission was accepted, re-completing it, then doing another mission. Afterwards, talking to Vilkas starts the mission the way it is supposed to and it can be completed.
360 If Vilkas's "Purity" quest is accepted before Farkas', the quest status may switch to "completed" even though it has not been completed. Also, Vilkas will not follow the Dragonborn to Ysgramor's Tomb.
This can be resolved by accepting and finishing Farkas' "Purity" quest first, being sure that the quest giver is following the whole way through.
A quick fix is to exit the conversation when the speech choices are, "get up,""are you better," or "I have killed it," then spam "use" on the altar.
Sometimes after activating the Flame of the Harbinger, the Dragonborn will still have the same number of Witch Heads as before.
This can be fixed by dropping and picking them up at the altar.
Another possible fix: Get a Glenmoril Witch Head in one's inventory. Then, ask the brother to be cleansed to follow. Travel to the tomb by any means and stand next to the fire. Tell him it is time to part ways, then speak with him again and accept the quest and kill the wolf spirit.
PC If all above fails, then use console commands:
setstage cr13 10 – this restarts the quest
setstage cr13 20 – if there is a witch head already in inventory
setstage cr13 100 – finishes quest
360 If one does not get cured immediately after "Glory of the Dead," the Flame of the Harbinger cannot be used unless a side contract from both Farkas and Vilkas has been completed.
Do one contract from each of them, then the second time one asks for work they will start the "Purity" quest.
360 Vilkas may not leave Jorrvaskr even after he has already been talked to about being cured.
This may be fixed in this manner: Walk back in and talk to Vilkas, "Purity" quest should be in the completed bin, he should offer work. If he does accept it and finish the mission he gives. When the mission is completed, Farkas and Aela should now offer work. Talk to Farkas and he will ask to be cured, take Farkas to the site and cure him. The Dragonborn should now be able to have a follower. Once Farkas is cured, Vilkas should do "Purity" with him without him bugging out.
360 If Farkas is married to the Dragonborn, he no longer gives quests, even though the quest indicator says that one can get work from the Companions.
360 Jorrvaskr may not be able to be exited.
360(Fix) This can be fixed by disabling autosaves. A black screen appears. Activate the map and move until hearing a click. While the cursor is hovering over a destination tap 'A' twice to fast travel. If the result is a black screen for more than two minutes the fast-travel has failed.
PC Vilkas may not be able to be dismissed as a follower. This is most likely after taking on the "Dragon Seeker" quest with him which cannot be completed because Bonestrewn Crest has already been cleared.
To cure the glitch: Create a manual save file before proceeding, in case something fails.
Then, go outside Jorrvaskr to make sure it is working correctly. Vilkas must be locked to the Dragonborn, blocking work from the other Companions. Enter the command resetquest cr14 into the console; this resets the "Dragon Seeker" quest with him; Vilkas will leave and go inside Jorrvaskr and no longer be a follower, but it still will not allow a new follower. Next, enter the command setstage cr13 200 to complete the "Purity" quest. With Vilkas that is bugged; it is actually active in the background but does not appear in the 'Complete' or 'Incomplete' quest lists. The Dragonborn will now be allowed to seek jobs from other Companion members. Immediately go find Farkas inside Jorrvaskr and ask him for work. He may do one of two things: Talk about never having seen a dragon and give his "Dragon Seeker" quest (If "Dragon Seeker" enables, fast travel to Northwind Summit).
Or, he may instead speak about something that is bothering him, ("Purity" quest). If this does not happen, reload the save file and try again. The "Purity" quest will now enable. Farkas will then say that something is bothering him and will give his "Purity" quest. If "Purity" enables, then proceed as normal. Once his "Purity" quest is enabled, he will remove Vilkas as a follower and become the new follower. Go to the Tomb of Ysgramor and proceed to the cleansing fire. Place a witch's head into the fire and kill Farkas's wolf spirit, then talk to Farkas and ask him if "he is alright." The quest can then be completed.
