- "So our blood runs as one, I'm Hidden Blade. Our darkness opened and we stepped into metal and rage."
- ―Hidden Blade.
Hidden Blade was a male Esh-kha who was born thousands of years ago during the height of his people's reign in the galaxy. In this time, he became a disciple of a new patriarch known as Hallow Voice who proposed a new way of thinking that involved peaceful co-existence with alien species. However, the Infinite Empire assembled its military might to crush the Esh-kha threat with the surviving members being placed into stasis on the prison world of Belsavis. The Rakata similarly captured Hallow Voice and his followers such as Hidden Blade that faced this sentence where they remained conscious but frozen in place for millennia. This changed during the Cold War when the Scorekeeper's Herald freed him from stasis.
