Star Wars: Shadow War
The Antarian Rangers are a group of trained soldiers and scouts who specialize in providing support for the Jedi. Founded by a Gotal named Kaskutal, the Antarian Rangers serve as field agents when the Jedi need resources beyond these provided by the Order. Though trained for combat, the Antarian Rangers also provide nonviolent support by offering Jedi transport services, supplies and other physical resources, and intelligence when working in the galaxy abroad. Though their efforts were not officially sanctioned or approved by the Jedi Council, many Jedi Knights trusted the Antarian Rangers with their lives.
When Supreme Chancellor Palpatine executed Order 66, the Jedi were not the only ones targeted. Antarian Rangers, long known to be staunch supporters of the Jedi, were branded as enemies of the state and collaborators who should be wiped out as well.Their numbers already diminished by the Clone Wars, the Antarian Rangers were all but wiped out by the clone troopers, much the same as the Jedi were, and they nearly faded into obscurity.
Also like the Jedi, many Antarian Rangers survived the purge by going into hiding. Small cells of Antarian Rangers continue to operate during the rise of the Empire, including cells at Toprawa and Tabiid. Though fleeing from the long reach of the Empire themselves, the Antarian Rangers ferry those few Jedi who survived the Clone Wars to safety, with varying degrees of success. As the Empire marches on, the Antarian Rangers become less like an active paramilitary group and more like an underground resistance movement.
