Hello all! I am currently working on an outline for my first fantasy novel. First, a little background. The world consists of islands, with one large center island, and 8 surrounding islands. It used to be one large land mass, but because of a conflict of Gods, the sea level rose, creating 8 islands. Due to lack of contact between men on the island-nations, culture evolved differently on each. The center island has a King (and a royal family) that has been given a "fountain of immortality", which just generally add many years to life. Hundreds of years before the story takes place, the King's men discovered one of these islands while sailing, and this led to the discovery of all other islands. While each island has their own "government" establishment, they all had to swear fealty to the center King, and let him rule over the islands. The story begins with the MC being raised by a noble families of one of the other islands. He is the illegitimate son of the King, and was secretly brought across the ocean so he wasn't killed off by the King (which was the norm). The story begins with all islands being "fed up" with the main island and they all want an assault against the island. While they all have different motives (grudge, some want of immortality, some want to rid the world of immortality) they all team up for an assault. The MC must decide whether to fight for his father or the islands. My main questions are as follows: Is the "fountain of youth" a plausible reason? Does anyone have any ideas for motives? Should the ending entail some sort of self sacrifice? (I kind of want an a-typical ending) I also wanted the bastard son to rise up, and lead the assault. But the issue I have is, why would the other islands want him to lead the assault? Thanks everyone for your help! Even if you have suggestions not listed, that would be an amazing help, and I would be more than happy.
