Siera's reign began when she challenged and defeated Kalamere Ar'din. It was during the time between her acquiring of the crown and her first defense that Baron Torquillian Aspendale retired his ring, leaving harsh words to Siera in his wake. He was vehemently opposed to Siera's kinship with Feadur Feamegil.
Siera's first challenge came from the winner of the Warlord's tournament, Valmion. Siera was victorious, however it was rumored that she overcame a deficit. Her second challenge came from the Warlord Ecore. Billy Ray Karnafexx issued Ecore a test of worthiness; one Ecore was never able to overcome.
Next up for Siera was Connor McCloud, and he also fell to Siera's blade. Siera's fourth defense came at the expense of Falire. Baron Feadur issued a test or worthiness to Falire, but was unable to defeat Falire's champion, the Baroness Halo. Little else is known about Siera's defenses beyond that. She was next challenged, and defeated, by Percival.
