Wild at Heart is a Side Quest in Velen, located in the town of Blackbough, where a hunter seeks his missing wife.

Wild at Heart Walkthrough

Head to the town, which is just Northwest of Crow's Perch, and find the man named Niellen. His wife disappeared one night, most likely in the woods near town. His wife's sister Margrit also has no clue where she could have gone, but points you towards two people she was close to.

Speaking to the butcher's wife, you'll learn that the wolves in the woods have been acting up, which is most likely where she met her end. The children she took care of at the Blacksmiths will also tell you they saw her entering the forest with another woman.

From Blackbough, head North into the woods and follow the long trail up past the Pellar's hut and into the deeper part of the woods. As you enter the quest area, you'll see a large group of Wolves around a dead dog. Defeat them all and take care not to get cornered by their numbers.

At this point, a highly suspicious Margrit will approach you and ask you to stop looking, out of concern for Niellen's sanity. She'll attempt to pay you if you tell Niellen that you found her dead in the woods, to which you'll be awarded 72 XP for the bribe and 25 for telling him, and will get 55 crowns for the bribe, and an extra 10 for telling Niellen.

If you'd rather persist in finding her body, shrug Margrit off and inspect the dead dog. You'll find blood and claw marks of something big, and just behind the tree you'll find the broken body of Niellen's wife - killed by something big. The tracks will lead to a large tree with a stone slab propped up on it, and so you'll need to find a nearby tuft of hair to continue the search by smell alone. Follow the smells along a path to an Isolated Shack. Inside you'll find evidence that Niellen was doing his hunting from here...and much worse. Find his notes, and then search below the house to find a cave. At this point you'll want to meditate until nightfall and prepare yourself with potions.

Inside the cave, a Werewolf will stand before you with a few Wolf guardians (they will be classified as monsters, and so the silver sword will be needed to defeat them.) Take out the wolves and then move against the werewolf. Werewolves are vulnerable to several items, including Moon Dust, Devil's Puffball, Cursed Oil, and use of the Igni Sign. Use what you can to lower its health, and dodge out of the way of its leaping strikes.

When the werewolf is almost dead, it will fall down, at which point Margrit will run in and beg for you to stop, revealing the identity of the werewolf in question. Once the story has been revealed, you can choose to leave Margrit with the werewolf, or finish it off now. If you choose to finish it off, you'll need to whittle down the last bit of its health to kill it. If you leave them be, the Werewolf will do his dirty work, then ask that you kill him - no battle involved.

From the werewolf's corpse you can find a key to the locked chest in the Isolated Shack. This should give you a fair bit of rewards, including the diagram for a Crafting recipe for Shiadhal's Armor.
