Actually, here's a better idea. Go to Camp NaNoWriMo (https://campnanowrimo.org/sign_in), sign up, and start writing during the month of April. Write badly - everybody does when they start out.

Don't ask for help. Just start writing. Get stuff on paper or pixels. Deal with how 'good' or 'bad' it is later. Just create a rough draft.

This is the way people learn how to write, and not by asking others to help them or do it for them. You have to be the one who gets this ball rolling. Nobody else can do that.

A Kingdom....which century? a real one or a fantasy one? Which country or which continent?
Do as jesper suggested and use your fantasy and not other people´s.
