The planet Colstev, Jin-Rio’s home, is a smallish, rocky world in the Stewjon system. Most of the population lives in domed cities built into the craters that dot the planet’s surface. Colstev’s cities are large, cosmopolitan, and hotbeds of intellectualism, political rhetoric, and, according to people from the rest of Stewjon system, bossiness.

Jin-Rio was born and raised on Colstev and attended the University of Zo-Ro where she studied Political Science and immediately became heavily involved in local politics. Like many idealistic young university students, Jin-Rio marched on the capital of Colstev, read proclamations condemning Imperial cronyism and human-centric policies, and generally made a nuisance of herself at every opportunity. Due to Colstev’s long tradition of free speech and vitriolic political rhetoric, Jin-Rio and her comrades were caught completely by surprise when one of their peaceful demonstrations was interrupted by Imperial stormtroopers and AT-ATs. Hundreds of students died and the University of Zo-Ro was closed.

The Massacre of Zo-Ro, as it came to be known, was the watershed moment for Jin-Rio. She went into hiding as the ISB crawled through the city, rounding up any suspected dissidents and, on occasion, their families. Jin-Rio watched as most of her friends (those who had survived the massacre, at least) disappeared one by one. Seeing no other options, Jin-Rio fled the planet and joined the Rebel Alliance, vowing to return one day and restore democratic principles to her homeworld.

Now, Jin-Rio serves attached to Special Operations, where she lends her expertise as a Political Advisor to high-ranking officers such as Arkhan Brem’tu. She also engages in field missions to destabilize Imperial control and apply political leverage to recalcitrant civilian governments.
