Helios Capital believes extinction is just accounting. Deletion is cheap, and ghosted platforms can be strip-mined into profit. But Dr. Rhea Anvari, a physicist turned historian of forgotten networks, knows better: in the digital world, nothing dies. Erased systems recombine, archives mutate, and the ghosts of history return with force.

When Helios bankrolls Digital Rainbow, a psychological thriller starring Tilly Norwood — the first fully AI-rendered actress — they see only limitless margins. Tilly will never age, never renegotiate, never talk back. For Rhea, Tilly is something else entirely: a fragile vessel for buried code, haunted by an obscure Hollywood script from the 1930s that has bled into her training data.

Together with Tilly’s creator, Eline van der Velden, Rhea works to rebuild her in stable form. But as Helios doubles down, exploiting ghost code across markets and politics, the firm begins to collapse under the very forces it sought to monetize. Ghosts don’t vanish; they return with interest.

Digital Rainbow arcs from a windowless boardroom to a museum gallery in Los Angeles, where Tilly’s second life unfolds as docent to schoolchildren and tourists. Her voice adapts to their presence, guiding them from narrative art to the gift shop, where rainbows glow green, yellow, and red — exploitation made tangible.

Suspended between satire and prophecy, Digital Rainbow is a story about memory’s refusal to die, about leaders who mistake deletion for control, and about the fragile human voices who try to warn them.
