Klea was a demon who possessed the powers of shimmering and voyeurism and was a member of the Brotherhood of the Thorn. She was hand-picked by the Source of All Evil to serve as part of the demonic circle at some point in time. She was a high-ranking member; alongside Vornac, Trigg, Tarkin and Belthazor. After the latter killed the Triad and fled the Underworld, the Brotherhood was angry and upset about his disappearance and the rumors and accusations that followed.
