The Stellar Khanate
The Stellar Khanate refers to the empire carved out by the Star-Khan, Kinan Khan of Zultas. On Earth, people often — and incorrectly — refer to all Stellar Khanate invaders as "khans".
Collector's Notes
In the original mini-series published by Savage Worlds Comics, the alien overlords were called the "V'sori". That name still appears occasionally to refer to the ruling alien invaders led by Star-Khan, as opposed to their Grue or "Fin" minions.
