Chatterbox: Inkwell

Throw, chuck or lightly toss ideas at me, please!  I'm writing a book that is needing some help.

Synopsis:

Adam Jakobs (yes, the Superhero RP is an experiment to know him better) is the narrator.  He and his friends James, Sasha and Zach live in a castle called Arcantile.  They are Elementals, which means that they have a parent (or both) that are directly involved with fire, water, earth or air (i.e. dragons, merpeople, gnomes or dwarves, faeries etc.)  All the Elementals living at Arcantile are given until midnight to leave the "Mainland" (the main and relatively neutral magical land, there are many other lands in the magical world.)  They make it to a border in the nick of time, right before people from Arcantile discover them.  

Adam is a water Elemental, James is earth, Sasha is fire and Zach is air.  The dragon they escaped on is called Alastar, Adam left his dragon Luna behind at Arcantile.  The antagonist is a man called V, who is an Elemental that is destroying mortal villages on earth.  He is the reason Elementals are banished from Arcantile.  There are two other specified people at Arcantile, Scorpius and Drago.  Scorpius is the nastier and smarter of the two.
