After having finished "The Quest" I have realized that the "Quest" that Taita and Fenn go on does not start until the end of "The Quest".
This implys another sequal!
Here's my suggested plot line for Quest II:
After Fenn has her second eye opened in India (that's sooo gross!), they make their way back to Egypt. There, Taita and Fenn are able to 'see' the new home of the Fount. It lies far to the west, across the Great Sea. Taita assembles a fleet of ships capable of crossing the Great Sea and lands in America, circa 1600 BC.
After many adventures in America, they make their way to the Kingdom of the Aztecs and to their capital city on the lake. There, a large volcano smolders nearby. Taita and Fenn find the entrance to the Fount and Fenn becomes immortal. Taita becomes the mythical figure known as Queztalcoatl and travels far and wide throughout Central and South America, leaving many "white" decendants behind.
On the coast of Peru, they build another boat and set sail across the Pacific Ocean... end of Part II.
What do you think?
