Elaine is Kelvin’s scion companion AI, whose code was enhanced in the ancient Emissarian language by his best friend Ben at April LaCroix’s request, four years before the start of the story. The modification came from the continuum stone housed in the chamber beneath the Atlas. She is modeled after King Arthur’s little-known middle half-sister, younger than Morgause and older than Morgan Le Fay, but in truth she is far more than she appears. Her alliance with Kelvin and Ben makes her one of the story’s most significant figures, while her rocky relationship with the Architect Montegarr gradually warms as the narrative unfolds.

Visually, Elaine is a striking, ethereal blonde woman with long, softly waved hair, often styled with a vivid green braid. She has porcelain skin, vivid blue eyes, arched brows, and a composed, regal expression. In Camelot, she wears emerald-and-ivory ceremonial gowns with ornate gold embroidery and draped sleeves. At the Atlas, she appears in a sleek white tailored suit with pale green ornamental detailing, polished accessories, and a luminous nightclub presence. Across both settings, the ankh at her neck remains visible, reinforcing her calm, commanding, otherworldly beauty, part queen, part priestess, part social sovereign.
