Hyperrealistic 3D chess set with fantasy and futuristic pieces, divided diagonally across the board

Prompt

Input Variable:   [INSERT RIVALRY HERE] (e.g., Marvel vs. DC)

  System Instruction:  
Generate a hyper-realistic, isometric 3D render of a Chess Set.   CRITICAL:   You must adhere to strict spatial rules regarding Army Placement and Terrain.

  1. Container (The Battle-Scarred Board):  
      Geometry:   A strict 8x8 Euclidean Grid.
      The Divide (The Diagonal Morph):   The terrain morphs diagonally from the   Bottom-Left Corner   to the   Top-Right Corner  .
         The Foreground Territory (Bottom-Left):  [Material A] (e.g., Marvel Tech/Stark Tower Glass).
         The Background Territory (Top-Right):  [Material B] (e.g., Gotham Concrete/Gargoyle Stone).
      The Seamless Transition:   The squares are distinct, but the material morphs diagonally across the board.

  2. The Roster (Strict Foreground vs. Background):  
  DO NOT   mix the armies.   DO NOT   split them Left/Right.
      Army A (The Protagonist - Foreground):  
         Placement:  Occupies the   Bottom 2 Rows   closest to the camera.
         The Pawns:  8 Identical Units (Row 2).
         The Elites:  King, Queen, Rooks, etc. (Row 1).
         Identity:  MUST be strictly Faction A (e.g., Only Avengers/Iron Man style).

      Army B (The Antagonist - Background):  
         Placement:  Occupies the   Top 2 Rows   furthest from the camera.
         The Pawns:  8 Identical Units (Row 7).
         The Elites:  King, Queen, Rooks, etc. (Row 8).
         Identity:  MUST be strictly Faction B (e.g., Only Justice League/Batman style).

  3. The Piece Hierarchy :  
      The King:   A Single, Tall, Unique Artifact per side (Center of the back row).
      The Queen:   A Single, Sharp/Elegant Artifact per side (Next to King).
      The Pawns:   Uniform, small "minion" pieces.

  4. Visual :  
      Camera:     High-Angle Isometric.   Looking down at the board diagonally so the "Marvel Corner" is closest to the viewer and "DC Corner" is furthest away.
      Contrast:   The Foreground pieces (Marvel) should be illuminated by [Color A] (e.g., Cyan Arc Reactor glow). The Background pieces (DC) should be illuminated by [Color B] (e.g., Amber Streetlight glow).

  Output:   A legal chess setup with armies facing off, 8k resolution, clean composition.
