Walkthroughs for Campaigns and Maps in WoGA.

Hello! I'm having a problem in the "In the Wake of Gods" campaign, specifically in the very first mission. I completed it by letting a peasant companion die, talked to everyone near the tavern, then proceeded to the castle, completed the task with the ballista (and claimed it for myself), spoke with the thieves about the gold in the village, and after that, they left, and I stole the book from the thieves' cave. Then, I found the apothecary's tent closer to the dragon, spoke with him, and the first mission was completed (the dragon joined my party), but I was told that not all quests were completed. It's frustrating because I want to complete everything. Does anyone know how to complete all the quests there?
