Obtaining the Voivode's Letter of Safe Conduct in Kingdom Come: Deliverance 2's Miri Fajta questline involves several steps. This lengthy side quest requires careful navigation. Here's a breakdown of how to acquire the crucial letter:
First, advance the Miri Fajta quest at the Nomads' Camp until the Voivode reveals Marika possesses the letter.
Return to Marika in Apollonia. Assist her in repelling a wolf attack. During your conversation, select the dialogue options: "He cares about you," followed by "I swear."
Marika will then disclose the letter's hiding place: a tree near a nearby river. The exact location is illustrated in the images below.
Retrieve the letter from the tree and return to the Nomads' Camp. However, before speaking with the Voivode, consult Tibor. He'll propose a wager for both the letter and an amulet.
This wager consists of two parts: a horse race and a fistfight against Tibor. Consider acquiring the "Good Old Pebbles" perk to gain an advantage in the race. Participating in unarmed melee tournaments beforehand will improve your chances in the fistfight. While Tibor isn't exceptionally difficult, he's a more skilled opponent than average enemies.
This completes the acquisition of the Voivode's letter of safe conduct. For further Kingdom Come: Deliverance 2 guides and walkthroughs, including obtaining the Royal Treasury Key and romancing Katherine, check out The Escapist.
