High Galactic (Earth-2356)

High Galactic is a writing system notably used in certain Galactic Basic holofeeds displayed on the planet of Coruscant, then capital of the Galactic Empire. Algebraic formulas could also be written down in High Galactic letters. The bottles containing the Nabooan wine called Domaine de la Maison sur le Lac also featured High Galactic characters on their stickers. Janyor of Bith's book on propaganda features examples of persuasive artwork that used both Aurebesh and High Galactic copy executions.
