The wedding of Lord Semine and Agnes in *Kingdom Come: Deliverance 2* isn't going smoothly. Lord Semine's ceremonial sword has vanished, and you're tasked with its recovery. Here's how to find it.
Finding Lord Semine’s Sword
Radovan reveals the missing sword, a gift you crafted from the Hermit's Sword. He saw a man in yellow acting suspiciously. Your search begins with finding anyone in yellow clothing.
Questioning those in yellow yields little, but someone mentions seeing a yellow-clad man heading upstairs in the stable. Investigate! You'll find Hans, romantically involved with a woman.

While Hans isn't the thief, he witnessed Svatya (the bailiff's son and the bride's brother) taking the sword. He didn't follow, so you must find Svatya.
Confronting Svatya
Svatya is near the musicians playing for the wedding guests. He's easily spotted drinking by the stable wall, sword in hand.
He confesses to stealing the sword to embarrass Old Semine, believing the elder Semine's actions warrant it. He regrets his impulsive act, realizing the potential consequences. He reveals he tossed the sword into a nearby pond.
Retrieving the Sword

The pond is behind Radovan. Locate it, and you'll see the sword in the water. Retrieve it.
Return the sword to Radovan. You can either reveal Svatya's actions or simply focus on the sword's recovery. Once the sword is returned, the wedding ceremony proceeds. Complete any time-sensitive tasks before speaking to Radovan, then congratulate the happy couple and continue the main quest.
