The star produced no light and was hidden. But he could sense it. He could also feel the terrible power that the star was about to unleash.
He looked in the direction of the star and saw that it was the spacecraft. It looked normal. It was just floating there in the air, thousands of kilometers above the ground. But Kelvin knew without a doubt that the spacecraft was pretending.
His eyes lit up in realization. "It is cloaking."
As soon as he had that thought, the cloak of the spacecraft fell. It had finished its preparations, so it made its move.
The ordinary look on the spacecraft disappeared immediately. A white ball of light was in its giant cylindrical maw. That maw was also pointed at them.
Kelvin's back tingled in the telltale sign of danger. He cursed out loud, "This sneaky bastard is going to cook all of us."
