The damaged neurobionic prototype is surgically removed from Lyria and destroyed at her insistence, ending its promise of power without sacrificing her memories.
The psyche was the damaged neurobionic device that entered Lyria after the Figment's death. Its potential was immense—machine command, enhanced body and mind, and access to linked systems—but its repair threatened to alter the explicit memories through which Lyria held her family and losses. She refused that bargain even when stranded in Matteo's asteroid refuge.
Matteo performs the maximally invasive removal. Lyria spends weeks recovering from the neurological disruption and then completes a final grid test that demonstrates her emotional memories and personality remain her own. Though the device's absence leaves a phantom sense of the security and grand destiny it once promised, she identifies it as an alien presence rather than part of herself.
At Matteo's direction, Lyria personally draws the command that destroys the inert psyche. Harsh light reduces its tiny core and thousands of translucent tendrils to liquid metal that drains away. Its technological threat and opportunity are over for her; the freedom it leaves is ordinary, precarious, and wholly Lyria's.
A tiny flat core with thousands of translucent tendrils like a halo of angel hair, inert in a metal basin after removal from Lyria's head before it melts into liquid metal.
The psyche is the rejected shortcut to power whose destruction confirms that Lyria will pursue Volga as herself rather than as a machine-made weapon.
