Tainted Earth Clan

The 'Tainted Earth Clan, due to offworld interference, possessed both lightsabres and the knowledge to use them. However, the Dark Lord Darius Malakai exterminated them in 17 ABY. Only a few survived, most as his captives. Some - blinded and used for experiments, and including the Clan Mother, Suli - were given to Velok as a gift of goodwill.
