I believe that the great King of the Black Knights was...
THE GHOST
The Black Monarch's castle did not have a king. The next Black Knight set was Black Monarch's Ghost right?
The name of the set implies that it is his ghost, therefore he (the ghost) is the king.
I also believe that, in his passing, the new king is none other than...
The knight who is meeting with him. If I am not mistaken, is this not the knight who first wears Euro armor and a pivoting visored helm? He then makes it a standard for the army, thereby making that faction the greatest faction ever!!!
BTW the Dragon Masters are not the same as the Black Knights. The Dragon Masters defeated the Black Knights because they cheated by using magic, and green dragons.
But...what happens when the Black Monarch summons the blue dragon of his shield?
The mighty, BLUE.......T-REX comes to his aid!!!!
Bwahahahahah!!!!
