My theory is that the leveller borns to remember the ppl to dont forget the old legends and wars, and to understand that they must be prepared always against him if they want to defend their lands.
Also i think that the leveller (like Balor or Moagim) are the bad parts of his old personas, those who saved the world. And i think that the mirror Tramist is involved in this, maybe those who see his reflect in it, become the bad part of himselves. Someone asked how Connacht becomes Balor? Any more theories?
Others hidden objectives is to make a good game like myth and to make a thread like this.
