13 parts Complete This story is discontinued, waiting for its re-write version but hey. You can read it if you want, nobody's forcing you. Especially the ending of the final chapter. I really love it.
2037, another usual year. On a normal day, in the afternoon in New York City, a weird shaped building that resembles a gate opens in the middle of the city. Suddenly, a medieval army with 30,000 soldiers that looks quite familiar with the Roman Empire bursts out from the GATE and cause chaos. What will happen next? What is this GATE? How many secrets does it hides from us?
