I just had an intriguing thought about a potential future story in my fantasy series. In my fantasy world, it is already known that meteorites contain an ore that creates high quality weapons and armor. However, what if something else comes from meteorites? What if a legion of predatory life forms were dormant in a cluster of meteorites until they crash landed? How will medieval and fantasy armies stand against a horde of otherworldly predators? These aliens will not have spaceships, lasers, or technology of any kind. They will just be purely instinctual animals searching for food. I will toy with this idea further as it develops.
