The usage of the term "quest" here is broad, as there is really no task that must be accomplished. Instead, the Sadhu presents you with a scroll containing what he has discovered from the previous quests and his interpretation of these findings. This concludes the Hindi chapter of the creation quest.
No reputation nor experience are gained from this quest. Instead, the Sadhu rewards you with the Book of the Sadhu and with the ability to, if so desired, move on to the Norman chapter of the Creation Quest by finding a villager in a Norman village where your reputation is Friend of the Village or greater. Also, if you wait a little bit longer, the Sadhu will allow you to take on the quest (again, usage of the term is broad) Leadership, an extra quest in the Hindi chapter.
