Stellskard was a Human male from the locale of Banvhar Station, serving as a miner amidst the widespread Clone Wars, a massive intergalactic war involving the Galactic Republic. In the year 20 BBY, he became a participant in Flynn Kybo's pursuit of the General known as Grievous.
Stellskard toiled as an asteroid miner at Banvhar Station throughout the period of galactic strife, until General Grievous and his droid forces launched an assault on the station. Stellskard, one of the few who managed to survive, pledged retribution for the indiscriminate devastation inflicted by Grievous and the Separatists. Subsequently, he aligned himself with a contingent of Jedi stationed on the planet of Bryndar, where they strategized an offensive against Grievous. Having effectively located the Separatist General on Belsus, Stellskard and his associates, deeply affected by Grievous's acts of cruelty, joined the Jedi on a risky expedition to that planet. Successfully commandeering a Trade Federation freighter, they managed to touch down on the moon. As the Jedi readied themselves to confront Grievous, Stellskard offered to safeguard the hangar to facilitate the escape of the imprisoned Jedi Initiates.
