Amplifies his lightsaber with the Force

Vader rushed through the ship, his anger going before him and parting the crew that otherwise choked the halls. He reached the hatch to the hyperdrive chamber. Four dead stormtroopers lay on the deck, and another group of stormtroopers and armed security personnel used a portable grav-ram in an attempt to force open the hatch. The control panel and door switch were dead, probably sabotaged from the other side.

The corporal in charge of the security team saw Vader approach and stepped out to meet him. Meanwhile, the ram powered up with a hum and slammed into the hatch, doing nothing.

“Lord Vader,” the corporal said. “The door’s been secured from the inside and the switch has been disabled. There’s only one other way into the chamber and I’ve sent a team around—”

Vader ignited his lightsaber.

“Move,” he said, not slowing, and the security personnel and stormtroopers nearly tripped over themselves as they scrambled out of his way.

He took his lightsaber in a two-handed grip, channeled the Force, channeled his rage, and slammed the blade into the hatch. It sank an arm’s span into the metal. The heat from the weapon made a red-hot circle in the hatch around the blade. Vader held on to the hilt and poured in his power. The metal started to surrender to the heat of his weapon, the heat of his wrath.

He would cut through the hatch within a sixty count, and then the traitors would be his.
