In the Risen series, quests are one of the primary means for both providing the Hero with experience and also advancing the storyline. In addition to individual quest pages and category pages such as this one, locations and NPCs will list quests associated with them. In these cases, quests are either of a primary or tangential association.
When a location is where a quest begins, it is considered a primary quest to that location. Similarly, whenever an NPC is the one assigning a quest or the one to whom a quest is turned in, that quest is then considered primary for that character. Conversely, a quest is tangential if a location is involved but not where the quest is started; it is tangential if an NPC is part of one step of the quest, but not the quest giver or the one officially making a quest complete.
