Thanks!
Realized I forgot to ask how system locations are referred to in-game.
My own approach, in-game, has been
Sector-name Sector-Hex System-name, such as
Fornast 1519, Decatur.
For more formal and pedantic roleplay, I use the UPP (UWP) in-game and add
World-profile in Subsector-name. So, when informing the vic.., er PCs, of their destined prison system, I'd say
Fornast 1519, Decatur System D545542-8 in the Akashganar subsector.
Formally referring to the main world, I add
Prime (and systems could have multiple bodies named after the system, usually with roman numerals added based on orbit, ala Decatur IV). The system name by itself was the name of the system's star (multi-star systems might use Greek letters, ala Decatur Alpha, with locals using their own preferred names).
Meta-game, I simply listed things as Sector-Hex System-Name in a sector listing.
