Getting into the main area of the castle is your main focus during Chapter 1 of Gothic 1 Remakebut to get there you must first complete a bunch of small missions.
People at Old Camp need to know they can trust you, so it's now your job to prove your worth. You can do this by talking to any named NPC and completing the side quests they have for you. There are some important quests to do to make sure you get into the castle and talk to Gomez, and also deliver the letter to the Fire Mage.
Walkthrough of Casting Shadows Main Quest
When you arrive at Old campyou must go to the castle entrance and tell him about your plan to join. He will explain that you need someone to vouch for you if you want to enter. Thankfully, you've already met someone willing to do this: Diego, whom you met at the beginning of the game.
Diego won't just vouch for you right away, of course, and need you to prove yourself first. You can do this by completing some side quests. Start talking to the men around the camp; ignore the Diggers and Shadows, though focus on the NPCs with names.
Use the links in each side quest below to help you easily complete each one.
The side quests you must complete before being considered are:
- The cult recipe: talk to Dexter and steal a recipe from Swamp Camp.
- A ring for fingers: talk to Fingers, whose hut is near Snaf's cooking pot, and steal a ring from a nearby hut.
- Out of sight: talk to Thorus and trick him into a job.
- Test of Faith: talk to Diego, who will send you to find a man named Ian at the old mine.
- Whistler's Sword: talk to Whistler in his hut near the market, who needs you to buy back his sword from Fisk.
- The Vanished Warder: talk to Sly who is usually near the north gate, and help find his friend Nek.
Once these are done, you should talk to Diego again, and he should be able to vouch for you. If he says you are not experienced enough, then challenge one of the men in the arena to a fight to prove your strength.
