Unlocking the wedding in Semine in *Kingdom Come: Deliverance 2* requires completing the blacksmith Radovan's questline, which includes the intriguing Hermit quest. This guide walks you through each step.
First, visit the Troskowitz tavern and speak extensively with Innkeeper Betty. Then, talk to other villagers—the alehouse maid and general trader are good starting points—to gather more details.
Examine the documents and then investigate the quest marker in Apollonia. You'll find a hut and a clearing with a black horse; examine the horse for your next clue.

Proceed to the hermit's hut. Without evidence, he won't cooperate. However, armed with your findings, he'll become more forthcoming. During conversation, select the options: "You're suspicious," exhaust all dialogue options about the clues, and then "Out with it!" He'll reveal his true identity as Konrad. Before giving up the sword, he tasks you with delivering a cross to a widow named Margaret.
Go to the cemetery near Apollonia, speak with Margaret, and give her the cross. This begins the optional "Sinful Soul" quest, which involves helping her bury Ambrose. You can return to Konrad immediately if desired.
After killing Konrad (which is often easier than fighting the Crusaders), speak with the Crusaders and offer to return the documents for Groschen.
Finally, north of the hut, find two tangled oak trees. The hermit's sword is lodged in the ground. Retrieve it and return to Radovan in Tachov to complete the quest.
This completes the Hermit quest in Kingdom Come: Deliverance 2. For more game tips and information, check out The Escapist.
