Then, the discovery of Harkon's plan is a huge event. It sets the stage for the conflict. The battles against powerful vampires, such as the ones guarding important items or locations related to Harkon's plan, are also main events. And finally, the climax where either the Dawnguard thwarts Harkon's plan or, if you side with the vampires, they move closer to achieving their goal of eternal night.
