I have written many short and full lenght stories and I am capaple of building characters and world from the ground up.
Present me with your idea, especially if there is a unique aspect you want included in your protaganist's or the antagonist's character, and permit me to let my imagination loose on you project.
I'll start with a detailed synopsis, a charater list and basic bio, work out a feasible, is you need it you be, core conflict and work up for the effect of this conflict on the antagonist and protaganist.
