In past lives the Queen’s Pawn has always been the Queen’s Lady-In-Waiting.
Though considerably less in power she tends to bear a remarkable likeness to Her Majesty.
Whether this is intentional or not has never been made clear to the public.
The secret lies in the breeding and cloning experiments conducted by the University of the Gears.
The Queen’s pawns are one of the very few species that can interact with the King spawn due to the fact that they are secretly related due to the same program.
Even though she remains the Queen’s favourite the Queen’s pawn has exactly the same chance as every other pawn to be promoted.
No favouritism is given on the field of battle.
