Whoever holds the Eye of Onyx rules the Kingdom of Sand, provided that the last SandWing queen is dead. Therefore, if Princess Blaze, Princess Blister, or Princess Burn were to have the Eye, they would have become queen, stopping the war, as Sunny did in The Brightest Night. Sunny had given it to her mother, Thorn, the leader of the Scorpion Den and the Outclaws. Afterward, Blister attempted to steal it, resulting in her death, as the Eye deemed her unworthy. Since the current queen hadn't either died, or given Blister the Eye of Onyx willingly, she was electrocuted and reduced to nothing but a pile of black dust. Thorn is the current owner of the Eye of Onyx.
