Prerequisite: Complete "The Merry Widow." | Suggested Level: 10
Visit Lindenvale a few days after completing "The Merry Widow" to find the ealdorman in a fit: a fake Witcher seduced his daughter. Agree to help track down this douche, then head to your marker in the cemetery just east of the town - you'll find some footprints there. Follow these to find the impersonator in the back of the graveyard. When some more villagers arrive, go through the dialogue as you please. The quest will end right after.
Contract: Phantom of the Trade Route
Prerequisite: None | Suggested Level: 23
This quest is found in the village of Benek, on the eastern edge of Velen. Speak to the refugee there to learn that his caravan has gone missing. Start your search by heading to your marker and using Witcher Senses to find some clues.
Once a red scent trail pops up, follow it to a large cavern where the refugee traders await. They'll tell you what happened - a Royal Wyvern attack. Head out the other end of the cavern to find two wyverns and two nests. Take them out and destroy the nests to summon the big bad Royal Wyvern itself.
Now you'll have to slay the beast. It can be a tough fight, but bombs, oils, and Aard will help. Slay the beast and return to the contract issuer in Benek for your reward.
The Truth Is in the Stars
Prerequisite: None | Suggested Level: N/A
Also found in Benek is an Old Sage. Offer him some food to learn your 'future,' then head to the marker on your map - it's a cave southeast of the village. Inside, you'll find the dragonsroot the sage requested, as well as a few Ghouls. Kill them, grab the root, and return to him to wrap this up.
Scavenger Hunt: Griffin School Gear
Prerequisite: None | Suggested Level: 11
North of the Hanged Man's Tree is an abandoned fortress called Hindhold. Make your way to the top and take out the harpy's nest, then search the top floors for a dead body. Loot Balstick's letter from it, then read to learn about some special diagrams you can track down.
The first is found at Lornruk, at the northwestern tip of Velen. To get inside the tower, you'll have to dive to the water far below and look for a small grotto that leads into the base. The chest you're looking for is found up a short ladder next to a grindstone.
The second diagram is found at the Dragonslayer's Grotto, just west of Downwarren. Head through this dungeon, battling Wraiths and avoiding poison clouds, to eventually reach a burial site. Take out the ekimmaras that guards it, then search the chests in the room for the remaining diagrams.
Contract: Woodland Beast
Prerequisite: Complete "Family Matters." | Suggested Level: 6
You can get this contract from the Notice Board in Oxenfurt - it's the only one considered a Velen job - and meet the commander who issued it far to the west, at the Pontar. He'll tell you of a "beast" that attacked a convoy nearby.
Head to you new marker, take out the enemies there, and use your Witcher Senses to examine the area. Something's off, so start tracking the footprints you find. When you reach a stream, cross over, take out the Drowners, and keep tracking. You'll eventually find the true "beast": a band of thieving elves. Take them out, loot their corpses, and return to the commander for your reward.
