Lady Trevael was a prominent spice lord of the Sevari species. She held sway over the mountainous Northern Frontier region of the northern hemisphere on Sevarcos II during the era of the Galactic Civil War. She and her people maintained independent spice mining operations, deliberately avoiding any agreements with the Galactic Empire.
Trevael served as the chieftain of a clan located on the northern hemisphere of the planet Sevarcos II. Her clan's primary activity was the operation of spice mines. Her people were hardy and favored extracting the spice themselves to prevent intervention from the Galactic Empire, which desired her to utilize incarcerated individuals for mining.
Trevael demonstrated proficiency with both her flashpistols and her wind rider. She actively participated in numerous wind rider competitions held on Sevarcos II against rival clans. Furthermore, she was exceptionally dangerous with a vibroblade, and she would readily engage in combat should any of her vessels come under attack.
