Biography
Ericka Keane was born in Russia and joined the FSB after her parents were killed due to her father's involvement with organized crime. She was then moved to the US and given an alias.

Affair with George Vickers
As part of her attempt to gain information, Ericka becomes involved in an affair with the HR director of the North Dakota Black Site, George Vickers. Her relationship to George Vickers is primarily as a dominatrix, allowing George to indulge in masochistic fantasies that he is ashamed to admit to his wife. Through this affair, Ericka is able to acquire vital information about, and eventual access to, the Omphalos.

Apocalyptic Visions
Ericka's contact with the Omphalos gives her a vision of "the Purple End of the World", later revealed to be the Maurisuvius Rift. Disturbed by this revelation, Ericka confesses her role as a Russian spy to CIA Agent Claire Madison. Claire reacts by having Ericka arrested, but when Operation Calico fails and the Maurisuvius Rift is opened, she realizes that Ericka's grim prediction was accurate and has her released from her holding cell. Ericka and Claire, using their shared bond with the Omphalos, collaborate on the Flash Bulb Initiative in an attempt to prevent the complete annihilation of their world.
