I like to start with simple, vague plots that grow more complex and continue to brew organically. So what about a plot revolving around a Fae warrior (my character) trying to defend her homeland? So, since the Fae live elusively in forests and mountains, we could say that the king or an otherwise powerful force is destroying said forest and/or capturing the Fae to use to an advantage? Or killing them off due to their dangerous and legendary power that could rival the powerful force? This could cause my character to travel outwards to find the source of the problem, and meet many other characters and conflicts along the way.
