Elee'n became Gaius's wife during his reign as Praetor of the Romulan Empire. She tried to convince her husband to end the Alliance with the Klingon and to give up his vengeful pursuit of Capt. James T. Kirk and the USS Enterprise.
Following her husband's encounter with the USS Yorktown, the Organians, and the loss of his mind, Elee'n declared that she would rule Romulus until her unborn child was of age. She then ordered Klingon Ambassador Kloor and others to Romulan territory, thus ending the alliance between the two empires.(TOS comic: "Romulans: Schism")
