The Hutt Gambit
Dashade are tall reptilians with dark skin, lamprey-like mouths, and powerful claws. In addition to their partial Force-resistance, they are resistant to radiation. They also have an ability to dissipate heat which makes them hard to detect using standard life-form sensors. They have also used their natural abilities to their advantage as elite assassins, mercenaries, and among similar professions.
The Dashade homeworld, Urkupp, was destroyed when the Cron Drift supernova exploded during the Great Sith War, wiping out the vast majority of the Dashade. Though they were rendered nearly extinct, remnant populations have been seen sporadically for millennia, but even today they are believed to be all but extinct.
