here's a good general glossary that helps your writing feel more star wars-y and, honestly, the star wars wookieepedia is pretty comprehensive, so you can find most of the info you'd need there, on the fly, with only moderate effort.
basically, though, the 'power' i'm referring to is the original members getting to add a premade to the list, so if you want, i can make you a custom and we can talk plot and connections and such.
