Here is the way Gothic handle with quest descriptions. After you talk to a NPC, you will get a new entry in your diary/journal. Then you can read what the protagonist has written:
Spoiler below!
"To become a member of Gomez' people in the old camp, I should get in touch with Thorus."
...
"Thorus told me I should speak with Diego, when I want to be one of his people in the old camp. Diego will test me."
"Thorus has instructed me to expel a bandit named Mordrag from the old camp. How I do that he has left me. In addition, no one may learn that Thorus behind it."
...
"Mordrag adheres at the South Gate on the back of the castle."
