The quests in this area provide enough XP to both, level up the character to 20, and level up a Genie to 20 using XP as well. This means that it is hypothetically possible for a character to level TOO HIGH for some of the later quests. The Watcher of the Earth is right around the corner from the starting position, offering a genie from the start with the quest The Birth of a New Age. Go easy on it for the first ten levels, though, at least until you start to get some of the Bonus XP or do some extra grinding killing.
