In *Kingdom Come: Deliverance 2*, the ongoing feud between Prochek and Olbram can be resolved during the Battle of the Frogs and Mice side quest. Here's a detailed guide on how to navigate this quest and bring peace to the region.
How to Start Battle of Frogs and Mice in Kingdom Come Deliverance 2
To initiate the Battle of the Frogs and Mice side quest, you must first complete either the Mice or Frogs quests for Prochek and Olbram. Once you've seen one of these quests through to the end, the Battle of the Frogs and Mice will become available. Start the quest by speaking to Prochek in Tachov or Olbram in Zhelejov, and then head to the pasture to begin.
Should You Side With Prochek or Olbram?
During the quest, Henry must choose between siding with Prochek or Olbram. However, there's a way to end the feud entirely, which we'll explore in detail below. To side with Prochek, talk to him in Tachov and say, "Let's get those Zhelejovites!" To side with Olbram, speak to him in Zhelejov and say, "Let's go and see those Tachovites!"
During the negotiations at the pasture, avoid trying to reconcile them directly, as this will only trigger the fight prematurely. If you can pass the dialogue check, one person from the opposing side will flee, making the subsequent fight easier. Winning the fight for either side will earn you some groschen.
How to Stop the Feud

For a more peaceful resolution, before heading to the pasture, ask Prochek or Olbram if they want to end the feud. Then, travel to Troskowitz to speak with Baliff Thrush. Choose the dialogue option, "You'd finally have some peace." Passing the subsequent dialogue check allows you to access the scribe's room and read the Troskowitz Chronicle. If persuasion fails, you can sneak in to read it, but remember to save your game first.
Engage the scribe and select the dialogue option, "Fecit, ordinem in regione ope clavi ferrei."

At the pasture, locate three oak trees aligned next to each other. Examine the middle tree to find a nail. Your options with the nail are:
- Leaving it in the middle tree will split the pasture equally between Tachov and Zhelejov.
- Putting the nail in the west tree will allocate more land to Tachov.
- Putting the nail in the east tree will allocate more land to Zhelejov.
The choice of where to place the nail doesn't significantly impact the outcome, so you can choose based on your preference or remain neutral. After deciding, speak with Baliff Thrush again, who will agree to end the feud. Then, bring Prochek or Olbram to the pasture to finalize the peace agreement.
After resolving the feud, speak with Baliff Thrush to receive the Master Studies I book.
This is how you can stop the feud during the Battle of the Frogs and Mice in *Kingdom Come: Deliverance 2*. For more tips and information on the game, be sure to check out The Escapist.
