When she left, she chose life in an Ashram Monastery (in the same order to which Green Arrow had once belonged to). The Ashram’s Exalted Master was later killed by a renegade monk named “Lars,” who intended to unravel the “Wisdom Key” that unlocked the powerful “Book of Ages.” Onyx sought Green Arrow’s help to defeat the villain. In the Ashram, Green Arrow and Onyx were defeated by Lars’ minions, and the monk took the Wisdom Key from Onyx. Upon opening the Book of Ages, however, Lars was vaporized.
Later, Onyx appeared in Star City battling a villain named “Barricade.” Barricade turned out to be Lars again, who had been revived by his underlings. The spell that had apparently killed him was reversed only as long as he remained in contact with the Book of Ages, but he was attempting to make the reversal permanent by possessing the Wisdom Key again. In a battle with Onyx, Green Arrow, and Black Canary, Barricade again met defeat, and was reduced to a heap of bones.
Following this incident, Onyx was not seen for several years. She briefly returned as part of Wonder Woman‘s team of super-heroines to battle Circe‘s minions.
