Clark sped to the entrance, noting the bodies strewn across the marbled floor with alarm. 
"Your mother's personal guard." He muttered, noting the more ornately crafted armor and badges of honor that were ingrained on their chestpieces and braces. If the Shadows could eviscerate even Hippolyta's personal guard, then-

Another scream of pain assaulted their ears, the duo speeding around a corner to find the heavy wooden double doors that led to Hippolyta's personal chambers flung open, the circular shaped room filled by several Shadows surrounding two Amazonians, blood seeping down from their shoulders as they wielded their blades, forming a protective barrier around Hippolyta, her salt and pepper hair matted with blood oozing from a head wound. 
"Get your mother out of here! I can handle the Shadows!" Although referred to by name, the assassins didn't take heed of the Man of Steel, instead choosing to further their assault on the besieged survivors. Clark shot two of the attackers out of the air with heat vision before slamming their heads into the ground, the marble cracking on impact. Behind him, a Shadow attempted to run him through with his blade before watching it split into several pieces. Whirling around with a vicious elbow, Clark knocked his third attacker out of commission with little effort. This show of force prompted one of the survivors to reach into a pouch located within his vestments and throw a circular object on the ground, thick plumes of smoke filling the room that made even Clark disoriented for a moment. 
"Diana?! Tell me that your mother is ok!" As the vapors cleared, their attackers were gone...and so were several trinkets and objects that had been mounted on the walls of the chamber. 
"Why would they..." The best person to ask about motive, he assumed, would be Talia. Maybe he and Bruce could team up on this one...with Diana. Of course. Hopefully when they confronted Talia, Diana didn't snap the woman's neck on the spot. 

Hopefully. 

He looked behind him at the hall to confirm no other attackers were coming before heading to Diana's side, where he hoped she could get her mother to recount events as she remembered. Maybe they could get some clue as to how the Shadows overpowered one of, if not THE most, powerful race of people on Earth.
