How is Dark Messiah connected to Heroes of Might and Magic?

Whoa, there are whole intrigues here. It all follows a pattern. A traitor appears, who betrays their faith and starts killing their own, the dragon turns away from them and begins to look among its loyal servants for someone to blame for all the work of eliminating the traitor. For Malassa, it's Railag and Ilaya, for Arkath, it's Wulfsten, for Silanna... probably Faydaen, for the spider Arantir. In short, the dragons don't do anything themselves. They can only help their loyal followers defeat the unfaithful.
