Way to unlock: Read the map.
Quest giver: - (M3,36)
To find the map, you have to seal a rift (M3,42d) in front of the entrance to a small grotto with the map inside. Of course, you can try to enter the grotto without putting up any fight, but this may be more difficult than it seems to be. After you read the map, go to the Northern edge of the map, above the farms. There, you will find a cave (M3,36a) with a treasure inside - collect the entire treasure to complete this quest.
Rewards for completing the quest:
- Experience (little)
- 80 Influence points
