Once a high ranking Lady of Avalon under King Avallach, Maeve became dissatisfied with the Fair Folk helping to guide the younger races, rather than ruling over them. When her cousin, the Morrigan, was placed on trial before Queen Danu for starting a war among humans, Maeve protested to the entire Court and brought great offense to the Queen. Maeve would probably have been punished as well, had news of Avallach being slain by a human not interrupted things.
When Oberon was named Avallach's succesor, Maeve joined forces with Madoc Morfryn, who felt as she did about the lesser races and became his second-in-command when he built a new Court and declared war on Oberon. She ruled the Unseelie Court at Madoc's side for ten years, until they were overwhelmed in battle and brought before Oberon to be tried. Oberon punished Maeve and Madoc by stripping them of their powers and banishing them to the outside world.
Madoc and Maeve separated. Maeve spent most of her time in Ireland and eventually rose to power as Queen Medb of Connacht, eventually marrying King Ailill. She became enemies with Cu Chulainn when he prevented her from conquering Ulster, but later succeeded in having the hero killed. She spent a considerable amount of time after her reign as a wandering teller of tales, doing all she could to make sure the Sidhe were not forgotten.
Eventually, she and Madoc found each other and renewed their alliance. They set up Maddox Technologies under the names Nicholas Maddox and Mavis O'Connor. When a young Angela Destine accidently mentioned that she was from Avalon, Maeve began investigating her, and eventually discovered that she was a gargoyle from the Manhattan Clan. Later she and Madoc captured the Manhattan Clan. Maeve took a sadistic amount of pleasure in interrogating Angela, and threating to gut Broadway, should Angela not cooperate. When Angela was freed, she attacked Maeve, slashing her face. However, it did not matter, for she and Madoc's powers had finally returned, and the two along with the rest of the Unseelie retreated to the Brocken.
During the Second Unseelie War, Maeve enacted many schemes of her own. She tried to persuade Prometheus to join the Unseelie Court; attempted to use the Hand of Nai-No-Kami to create a great earthquake destroying New York City; and cast a spell that was slowly killing all the males in New York City. All of the schemes, however, were foiled.
Eventually, it was time to begin the final assault. Madoc and Maeve both led the attack on the Eyrie Building and together interrogated Goliath to get the spell to reach Avalon. Maeve battled Elisa Maza, but their fight was cut short when Madoc was slain by Demona. Maeve herself was captured and brought back to Avalon by the Weird Sisters to be imprisoned.
Whether or not Oberon can keep one as cunning as Maeve imprisoned forever remains to be seen.
As one of the more powerful Fair Folk, Maeve's magical abilities were almost limitless. During her ten-thousand year exile, Maeve's powers were significantly reduced, and she could only change shape. Of course, she was also immortal. In both spans of time, she had the typical fay weakness to iron.
