Let me paint the landscape for you.
A large open field with rolling hills in the background.
A cloudy purple sky with lighting bolts peppering the scene.
Small fires dotted across the landscape giving off red lighting effects on the ground.
Bodies of fallen warriors, both of Eyedol’s and Gargos’ species decorating the land.
Catapults and large war-beast carcasses all around covered in arrows and other weapons.
Swords, spears and axes stuck in the ground.
Maybe a few skulls on spikes.
Basically an epic battleground, all of the bodies are cold and grey, its a necrotic scene that would perfectly fit Eyedol’s new design. Perhaps where Kan-Ra found his body chopped in two, with a giant portal opening upon Ultra activation that releases some kind of creepy lost souls and a large monster that starts feeding on the carrion as the storm intensifies.
Sorry I just had this image in my head and I had to type it out, the purple clouds and red fire is meant to remind you of the original KI logo since Eyedol is the OG boss of KI.
