Zona Luka

Zona Luka was a padawan of the Great Master Dominus. She battled alongside Cay Qel Droma on Ossus. Later she was captured by the fallen Exar Kun and turned to the Dark Side.  
 
Upon Exar Kun’s order of killing Jedi Masters during the Sith Wars, she engaged her master, Dominus, in combat. She struck him down with her lightsaber but he too managed to kill her with Force Lightning before dying. 
 
Three Jedi, Dace Diath, Qrrl Toq and Shoaneb Culu found her body afterwards and paid their respects.
