Taking a minor break from writing I was sorely tempted to go back into logo design. What I had in mind was a bit more elaborate than a typical brand logo and more of a crest or insignia for a nation. You have to start with the basics, which in this case was the core element. For this insignia the core would be the arms of a galaxy, representing the nation's dominance or an assertion of supremacy.
I went though a few revisions, settling on something less angular and blocky. The other core were the four great vassals of the nation, which would be represented by how they are bound to the galaxy in the centre - the core and the home realm. The gem at the top felt less cliche than two heads looking in opposite directions, and helped to congeal some of the other elements.
This was all based on a drawing I had worked on ages ago that was supposed to be a coat of arms. I never really went back to it. This insignia could perhaps be depicted everywhere - against starships, on offical forms and declarations, letters, tanks, aircraft, pretty much something that could be stenciled or easily applied.
