Post your ideas!

This is where we can share our ideas for stories and such. I know I have quite a few that have been cropping up in my head for a while, so I'll be posting here regularly in order to make sure I don't lose track of them.

I've been reviewing and revising my version of Raven King, and I have decided that I will not have any singular protagonist. The story will, in equal parts, follow Rose, Elizabeth, Artemis, and Arechos's daughter as they each have their own agendas that end up splitting the kingdom in four factions. Certain supporting characters will end up changing allegiances while others remain tied to one faction for the entire story. What do you guys think of this development?

I also have this idea for a futuristic Sci-Fi type of story as well, but it's not what you'd generally think.
The protagonist is a man from a very powerful and very corrupt family, who at the age of fourteen kidnapped his younger brother as a toddler to escape them. He steals a ship and leaves the system, finding a new place and a new home for himself to raise his brother and give him a normal life. A number of years later, when said brother is in this universe's equivalent of middle school, is when the story takes place. I'm actually going for more of a comedy route than action or adventure, just various antics and misadventures that the younger brother gets into while the older brother struggles with his job, personal life, and keeping agents from their parents at bay and ensuring that their secret isn't found out. What do you guys think? Could something like this work?
