Gargoyle

A WARRIOR GUARD DREV HACKER ADVENTURE. "Gargoyles have attacked hundreds of worlds. They destroyed every inhabitant, except on Earth. We were different. Somehow, the primitive inhabitants of Earth survived.” The Warrior could hardly mumble now. "Gargoyles travel through space, invade a world, destroy it, and then disappear without a trace. Scientists believe Pak-Avon may be the next stop. If that’s so, they’re doomed. No one can fight them."
