Aurebesh is the recognizable text language seen throughout the series now. This was first seen in the Star Wars Miniatures Battles publication, developed by Stephen Crane with West End Games.
The ISB (Imperial Security Bureau). The ISB has a major presence in the first season of the Rebels television series. It's first appearance was WEG's The Politics of Contraband. It's awesome to me that this kind of detail makes its way to the core of the franchise.
