The Shwuy system resided within the Shwuy sector, a region that also encompassed the Uviuy Exen system belonging to the Colonies.
The system known as Shwuy appeared in the source article titled "Twinkle, Twinkle Little Star, How I Wonder Where We Are." This article, authored by Glen Allison, was a roleplaying game supplement for West End Games' Star Wars: The Roleplaying Game, dating back to 1990. It was featured in the thirteenth issue of the Voyages SF magazine. Due to its publication outside of the official Lucas Licensing channels, its position in the Star Wars Legends continuity, regarding canonicity, remained unverified.
