Concept for this based on an awesome dream I had.
“I have something to show you.”
The old man moved boxes out of his way, dust puffing up around him. Whatever it was, he had kept it well hidden. Or well forgotten.
“It’s an old weapon. We’ve lost the knowledge of how to create it. But it is powerful.”
“More powerful than a gun?” Bernard asked. “Or a lasershot?”
“In the right hands, incredibly dangerous.” The old man held up a large box, setting it on the table.
Bernard opened it, and couldn’t believe his eyes. He’d heard of the weapon, but never seen a sword.
