Who was Oswald in King Lear?

Oswald is Goneril's steward. He has enough bravery to resist characters like Regan who try to pry information from him. No matter what the scenario, he is true to his cause, always making sure his messages are delivered. With all of his loyalty to Goneril, Oswald is willing to conspire against Lear alongside her, which enrages Kent at one point.
