Then, the members of the human crew begin scrutinizing the spacecraft, until they are attacked by a new villain, which was previously revealed as a new alien faction called the Banished.

Succeeding sequences show the battle between the aliens and the human forces, using their own weapons. The teaser concluded with the Spirit of Fire's Captain saying that they would see what kind of galaxy they had awaken to.
