Create an ethereal and mysterious artwork depicting an Aetherborn in the midst of its spectral transformation within the Aetherverse. The Aetherborn should be in humanoid form, but with its features constantly shifting and undulating as if shaped by the unpredictable forces of the Aether. Use a palette of otherworldly colors and subtle, ghostly details to convey the essence of raw Aether energy holding the entity together. The background should be a swirling, abstract representation of the Aetherverse, with the Aetherborn appearing to sway or dance within it. Capture the enigmatic and ephemeral nature of these beings as they exist between the realms of magic and reality. | Synthwave
