With the countless systems, devices, and functions of Alexandra’s Bane transformation, there needs to be a local, central computer to control all of them. With Lumina being the control mechanism, she needs a direct and full connection to the entire system. The control core unit is a special spheric computer, slightly smaller than a softball. It is the main hardware on which Lumina eventually transfers her own origin process, and is both by Alexandra and Lumina perceived as her true physical body. The computer has been made with specially designed hardware by Lumina, so that it’s extremely efficient at running an instance of herself. This way, even if Alexandra, and the core unit with her, would get disconnected from any network and completely lost, Lumina would still be in full control, as a copy of her is able to run on the small computer.
The device is encased in a lubed, rubber material, and inserted through Alexandra’s vagina, into her womb. This places it in the most secure location within Alexandra’s body, but also acts perfectly as a symbol of Alexandra becoming a vessel and surrendering completely Lumina, by carrying Lumina’s purest physical essence deep within her own body, as if becoming the core of Alexandra’s new existence. With Lumina’s origin process running on the special hardware, this is even more the case.
The outer covering of the core unit is made up of two layers. The inner layer is inflated with rubber cement, that once hardened has increased the entire device’s size so much, it cannot be pushed past Alexandra’s cervix any more. The second core unit layer acts as a sort of balloon, being extremely stretchable. It can be extremely inflated to various volumes, distending Alexandra’s womb and mid-section substantially, making her seemingly pregnant. It is also used as the temporary container for Alexandra’s urine, as the liquid is drained through the catheter and lands in here, slightly inflating the layer, until it’s drained again in a maintenance cycle.
