"What should we do with them?"

Keal shook with fear as he stood next to his SAEF crewmates. Everywhere around him was clear, yet he couldn't see the source of the voice.

"Kill them"

Keal heard a scream as his friend standing right next to him was sliced in half by an invisible hand. One by one, the SAEF crew was killed. Aliens were SAEF's specialization, but these aliens... He felt a sharp pain, like a sword. And as Keal died, he couldn't even look in the eyes of the person who killed him.
