Lieutenant Jack Strong leads his team of elite marines to a distress beacon in the far reaches of colonization. Expecting faulty equipment, they instead find themselves in the first stages of war against a species similar to mythical demons. The Colony is a fantastic short story of military warfare and science fiction, with an ending that will leave you questioning everything.
