"The year was 2018, and humanity lived peacefully until portals suddenly opened around the world. Nobody knows where they came from, but it is known that after the arrival of these portals, legionary groups and knights mounted on dragons and creatures crossed into our world. In some cities, there was chaos, while in others, local police with the help of the army managed to stabilize the occurrences. But some countries were not so lucky, with high losses of civilians and local police.

After the incident, NATO countries and extra-NATO allies decided to set up a task force, Task Force 456. A task force whose main countries are the United States, Germany, France, United Kingdom, Denmark, Poland, Japan, South Korea, Brazil, Israel, and Australia. Together, these countries decide to carry out a mission on the other side of the world."
