Welcome to Naval Officer Training. I am Lieutenant Torrie Johanessen. In this class you will come to know every Ki of our fleets, but first, you won't be going anywhere if you don't know a little something about this galaxy that we call home. Most of the galaxy that can be seen in this image is part of the Galactic Arms. These are large spirals of gas and dust that originate from the Core. Do you see these gaps between the arms? Well, they really aren't gaps at all. They have stars and systems just like the gaseous parts of the galaxy.
