Vilkas

"Come to me with questions. I know our history almost as well as Vignar by now. Except I can remember it."

- Vilkas

 is a Nord lycanthropic resident of Whiterun, and the twin brother of Farkas. He is a member of The Companions and The Circle, the secret order within the Companions. He serves as the Dragonborn's shield-brother in several of the Companions' quests. As with all Companions, he is usually found within Jorrvaskr, located in the Wind District of Whiterun.

Quests

 * Take Up Arms: Prove that you're worthy to join the Companions.
 * Purity of Revenge: Retrieve the Fragments of Wuuthrad and wipe out the Silver Hand.
 * Glory of the Dead: Cure Kodlak Whitemane's spirit and prove to be a true Companion.
 * Purity: Help a member of The Circle give up their beast blood.
 * Escaped Criminal: Track down and kill an escaped prisoner.
 * Rescue Mission: Rescue a kidnapped citizen and escort them to their home.
 * Dragon Seekers: Defeat a dragon with Vilkas or Farkas.

Background
Vilkas and his brother, Farkas, were both raised in the Companions' Hall. Their father, Jergen, left them there while he went to fight in the Great War and never returned. Eventually, Vilkas and Farkas both officially joined the Companions. They were said to be the youngest members to ever join, though this may be a play on words by Vignar Gray-Mane, referring to the twins' young age during their residence at Jorrvaskr rather than the age at which their membership became official.

Personality
At first, Vilkas seems to think the Dragonborn isn't worthy of being a Companion, but he eventually warms up to the idea after the completion of Glory of the Dead. Vilkas is well-spoken and considered to be an intelligent man by the other Companions, the counterpart to his brother's physical prowess. Vilkas, along with his brother Farkas and Kodlak, resists the call of the beast-blood, choosing instead to refrain from transformations. However, he struggles with the side-effects more harshly than the others.

Vilkas is also thought of as a hot-tempered man. For example, during Purity of Revenge, he does not hesitate to avenge Kodlak's death. However, he does later show remorse for his rash actions, as seen in Glory of the Dead, during which he refuses to complete his journey to Ysgramor's Tomb, feeling himself unworthy.

After Main Quest
After the Companion's questline is completed, Vilkas will eventually give the quest Purity. In this quest, he will ask the Dragonborn to cure him of beast blood. He is available as a follower and also eligible for marriage after completion of The Companions questline. Vilkas can also be selected to act as Steward for the Dragonborn if the  DLC has been installed.

 * If Vilkas is a follower, the Two-Handed skill can be trained in for free. Buy training, then check his inventory and take the money back.
