In the first papyrus (chapter) of the first book, Atlantis: Bearer of Fruit, we are introduced to a number of key props of which each has its own story. Three of these props, however, do not have their mysteries unwound in this first book. What are those three key props? Glad you asked.
The Crystal Frog:
Ausethen shows a crystalized frog that he just learned how to make in Alchemy Class. Faeraud inquires about the process and if it would work on humans. The connection for this process is not paid off until the second book, Atlantis: Fall of the Gods. If you read the papyrus (chapter) titled Speciation Crib, you will learn more about Faeraud's devious plans for this crystallization.
Hedge Plants and Poems:
In order to receive a better grade on their final exam in lab class, we learn that magic poems recited over hedge plants can cause them to quickly and thickly grow -- almost instantly. Faeraud remarks that he hates these plants, and rightly so, as they halt his advance when Ahteana uses them in the second book, Atlantis: Fall of the Gods. You can read this adventure in the papyrus called, Mighty An Icy Fortress.
There is a small commotion when Yapet drops something and knocks one of the ornaments (a globeaky or key) off of Areshia's sandal. We have to assume that he did something to this sandal, like exchange the globeaky on it, because later in this first book, he tries to keep her sandal, and by the time they meet up in the Agglomeration Forest he is trading globeakys again. The plot surrounding this key will be revealed in the third book, Atlantis: Rise of the Nile, due to come out end of 2014. Look for the papyrus called The Frosted Desert.
