Kiriazis welcomed all visitors to her planet by brutally murdering them. She spared no one, no matter how much they plead and begged to be spared as noted by the Zamorons. Not surprisingly, a Sinestro Corps ring found her. As a member she heeded Sinestro's advice on using her natural talents and abilities in frightening new ways with her power ring. Kiriazis tested these abilities on her own family and friends, slaughtering them. It is unknown what battles she participated in the Sinestro Corps War, other than killing several members of the GLC.
