Her character is derived from the earlier (and later separate) figure of Percival's sister, and possibly also from that of Arthur's sister.^[4] Under her "Amite" name she was furthermore linked to Amice from Meraugis de Portlesguez.^[5]

Roger Sherman Loomis's work The Grail: From Celtic Symbol to Christian Myth draws a connection between the concept of the feminine "Grail-bearer" and the sovereignty goddess of Ireland, Ériu, who grants the chalice to only the worthy. He also saw her derived from the Welsh and Irish goddesses Modron and Dechtire, through the figure and archetype of Morgan.^[6]

She first appears in the Prose Lancelot, a part of the Vulgate Cycle, as an incredibly beautiful woman named Heliabel but known as Amite (in one spelling variant of these names).^[7] Her first significant action is showing the Holy Grail to the near-perfect knight, Sir Lancelot.

In the version as told by Thomas Malory in Le Morte d'Arthur, based on the later Queste part of the Vulgate Cycle, Lady Elaine's father, King Pelles of the Grail castle Corbenic (Corbenek, Corbin, etc.), knew that Lancelot would have a son with Elaine, and that that child would be Galahad, "the most noblest [sic] knight in the world".^[8] Moreover, Pelles claims that Galahad will lead a "foreign country...out of danger" and "achieve...the Holy Grail".^[9]

The sorceress Morgan le Fay is jealous of Elaine's beauty, and magically traps her in a boiling bath. After Lancelot rescues her, Elaine falls in love with him, only to find he is already in love with Queen Guinevere and would not knowingly sleep with another woman. In order to seduce Lancelot, Elaine goes to the sorceress Dame Brusen for help. Dame Brusen gives Lancelot wine and Elaine a ring of Guinevere's in order to trick Lancelot into thinking Elaine is Guinevere.^[10] The next morning, Lancelot is most displeased to discover that the woman he slept with was not Guinevere. He draws his sword and threatens to kill Elaine, but she tells him that she is pregnant with Galahad and he agrees not to kill her, but instead kisses her.^[11] Lancelot departs, and Elaine remains in her father's castle and gives birth to Galahad.

Thereafter, Elaine comes to a feast at King Arthur's court. Lancelot ignores her when he sees her, making her sad because she loves him. She complains of this to Brusen, who tells her that she will, as Malory tells, "undertake that this night he [Lancelot] shall lie with [her]".^[12] That night, Brusen brings Lancelot to Elaine, pretending that it is Guinevere that summons him. He goes along, and once again is deceived into sleeping with Elaine. At the same time, however, Guinevere herself had summoned Lancelot and is enraged to discover that he is not in his bedchamber.^[13] She hears him talking in his sleep, and finds him in bed with Elaine. Guinevere is furious with him and tells him she never wants to see him again. Lancelot goes mad with grief and, naked, jumps out a window and runs away.^[8] Elaine confronts Guinevere about treatment of Lancelot; she accuses her of causing Lancelot's madness and tells her that she is being unnecessarily cruel. After this, Elaine leaves court.

Time passes in the story, and Elaine next appears when she finds Lancelot insane in her garden.^[14] She brings him to the Grail, which cures him. When he regains his mind, he decides to go under false name with Elaine to the Isle of Joy, where they live together for several years as husband and wife.^[15]

Elaine of Corbenic is often passed over in favor of Elaine of Astolat. Like the more famous Elaine, Elaine of Corbenic is in love with Lance. Yet unlike Astolat, she is successful in both bedding and marrying Lancelot. Despite this, she has been traditionally overlooked by literary analysts. One theory for why she has been so ignored is because of the moral ambiguities of her actions.^[16] She does not fit into a neat category of female characters; she is neither good nor evil, but something in between.

According to Richard Cavendish, "Lancelot's experiences with Morgan and Elaine form a counter-point to his involvement with Guinevere. The theme of a fay or enchantress falling in love with a knight and trying to keep him her prisoner in the otherworld occurs frequently in the Matter of Britain. Elaine is not described as a fay, but she comes from the otherworldly Grail castle and Lancelot takes refuge with her from the human world in the enchanted Joyous Isle, where there is no time."^[17]

Elaine appears in the 1939 novel The Once and Future King, by T.H. White. Although the basic character does not change, there are several key differences. Time is more definitely specified in this version; for instance, when Elaine finds Lancelot in the garden, Galahad is three years old. Additionally, Elaine and Lancelot live together as husband and wife for ten years and actively raise Galahad while Lancelot bears a pseudonym to hide from the court at Camelot.^[18] Another key difference between White and Malory is that in White, Lancelot is cured of his insanity by seeing Elaine, but becomes physically sick and is nursed back to health by Elaine. White also chronicles Elaine's final fate, having her commit suicide when it becomes clear that Lancelot will never truly love her or end his obsession with Guinevere. He therefore combines her with the character of Elaine of Astolat, who is not referenced in the novel.^[18] Howard Pyle, too, conflates Elaine of Corbenic with Elaine of Astolat in his Arthurian book series.

Elaine also appears as a character in The Mists of Avalon by Marion Zimmer Bradley. In this version, she tricks Lancelot with the help of Morgaine into sleeping with her by making him believe she was Gwenhwyfar. Her father finds out and forces Lancelot to marry her to keep her honor. She and Lancelot, in addition to their son Galahad, have two daughters by the names of Gwenhwyfar and Nimue, who later becomes a priestess of Avalon and is used to trick Merlin into coming with her to the isle to receive punishment for perceived crimes against the Goddess and later drowns herself. Unlike the Elaines in earlier stories, she dies of natural causes later in the book.

A more contemporary novel is Elaine of Corbenic by Tima Z. Newman.^[19] Based on Malory's account of the three brief encounters of Launcelot and Elaine in Le Morte d'Arthur, it chronicles Elaine's journey through abandonment to the finding of inner strength and deepening wisdom.
