From the floor rose three humanoid figures made of liquid silver. They had no faces, only a single, glowing red eye in the center of their chests.
"Sentinels," Kaelen hissed.
The silver figures moved with a terrifying, fluid speed. One lashed out with a limb that turned into a blade, narrowly missing Kaelen's head. Lyra dived under another, her glass blade striking the silver skin, but the liquid metal simply absorbed the impact and reformed.
"They aren't physical!" Lyra shouted. "My blades won't work!"
"Use the Aetheria!" Kaelen roared. "Disrupt their frequency!"
