Complete the Buried Past quest by visiting Volk for multiple days and helping around the house in The Blood of Dawnwalker. You don't need to help him, but it will lead to a different outcome. Coen will learn more about his father's past thanks to Volk, so here's how to complete the Buried Past quest in The Blood of Dawnwalker.
You need around 4 days to complete the Buried Past quest in The Blood of Dawnwalker. Volk won't take up the entire day, just a few time segments if you decide to help around.
To trigger the Buried Past quest, you need to speak with the merchant located in Maragir. He mentions how you look like Pieter and points you to a secret location he used to go to a lot, after handing over some Slivovitz.
Head to the marked area between Svartrau City and St. Tyna's Grove to see a half destroyed hut. Inspect the tree and snares around it before entering the shed to inspect it.
A cutscene starts where Volk appears and fights Coen, trying to kick him out. After losing the fist fight and confirming your Pieter's son, he invites you inside.
Make sure, when speaking with Volk during any visit, to inspect around the hut and exhaust all his white dialogue options. This will make him reveal more information and ask Coen to help around. Otherwise, you might not get the optional objectives.
Here's what you can do after your fist fight with Volk:
There is another way to deal with the wolves for Volk without wasting one time segment. Don't mention the snares to Volk and when you're done with him, travel east of the hut towards the question mark.
