Medieval Dynasty

As far as I am aware, the main quest consists of Uniegost's Story I-VII. My assumption comes from the fact that it's the main focus of the story and finishing Story VII gives you a cutscene.

The first three quests are mostly back and forth talking to people across a day or two. It's easier to turn on Unlimited Stamina so running back and forth between these locations doesn't become a slog. I also recommend exploration/home development to make some of the fetch items easier to obtain.

For Uniegost IV, return to Sambor and start heading west until you reach Wolrad's village. If you want, you can try and get 1000 logs for a secret achievement. Otherwise, talk to him and progress the quest. At the next stage, you can either kill the cow or gather 30 meat instead. Talk again and return to Uniegost.

For Uniegost V, Sambor asks for 20 Beetroots, Onions, Cabbages, and Carrots before telling you where to find Kestrel. Once you do, you'll need a potion of Sobriety. This can either be bought, crafted, or found at one of the random carts on the roads. Listen to her speak and move to the next quest.

For Uniegost VI, you must find a medic in the woods. Talk to him and return to Kestrel. She sends you to find Domagoj who needs a crossbow before helping. Like the potion, this can be found or crafted. I took a wooden crossbow off a bandit right outside of Doma's village. After that, you'll need 500 coins, a waterskin with water, and 20 pieces of dried meat. Bring it to Kestrel.

Uniegost VII is just talking to the medic and returning to Gostovia to speak to Uniegost himself.

Hopefully, that's all that's required. Prepare for walking.
