In *Kingdom Come: Deliverance 2*, the wedding between Lord Semine and Agnes hits a snag when the sword meant to be Lord Semine's gift mysteriously vanishes. Your mission is to locate Lord Semine's sword and ensure the ceremony proceeds smoothly. Here's how to find it:
Radovan informs you that the sword, crafted from the Hermit's Sword for Lord Semine, has been stolen. He mentions seeing a suspicious man in yellow earlier, setting you on a quest to find this individual. As you roam the area, you can approach anyone dressed in yellow to inquire about the sword. Most will deny involvement, but some will hint that they saw a man in yellow head upstairs in the stable.
Finding Svatya is straightforward. Exit the stables and look towards the musicians entertaining the wedding guests. Svatya is drinking by the wall of the stables, to the right of the musicians. Upon approaching him, you'll notice he has a sword, raising hope that it might be the one you're after.
However, Svatya confesses that he's already disposed of the sword, having thrown it into a pond to embarrass Old Semine by making it seem like he lost his son's gift. This act was intended to paint Old Semine as forgetful, though Svatya didn't consider the repercussions or his father's stance on theft.
When you return the sword to Radovan, you can choose to reveal Svatya as the thief or simply say it's no longer important now that the sword is found. Either way, the ceremony can proceed. Make sure to complete any pre-wedding tasks before speaking to Radovan, then congratulate the newlyweds and move on to the next main quest.
