Insight quest is a lore-centric, classic adventure-type quest that resolves some mystery or knowledge gap by providing required information.
Similar to mystery detective with fantasy elements, used to add depth and subtle content that defines the character of then game.
Keys ideas;
1.Players searches for clues, new information.
2.Each part unlocks new knowledge/clues.
3.The goal isn't specific and provides no reward.
4.The quest isn't time-limited or mandatory.
5.NPCs have conflicting or incomplete information.
6.Quest is focused on exploration and puzzle resolution, not combat(though it may appear in background).
7.Avoid giving explicit tasks: NPCs only give hints and don't "give you a quest".
