The Duality is comprised of Queen Mysha & President Komal, the two act as the de facto rulers of Phantasmagia. Prior to their separation, The Duality existed singularly as The Old God.
Immediately following the split, it was widely reported there was a heated argument between Mysha & Komal. The royal domain then went through rapid reconstruction, culminating in two mirrored castles.
All memories & information that The Old God possessed was lost in the split, thus the constituent parts consider themselves entirely separate from their original form.
