Remnant Cubes

Officially known as "Remnant Cubes," these advanced artificial intelligences were created for the Second Coming of Solaris using Encore's abilities and Tethys's microprocessing support.
The Remnant Cubes differ from their originals in subtle to outright obvious ways. The cause of these variations remains unclear. Is it the user acting as the anchor point, Tethys's scanning and data support, or Encore's artistic leeway as the master artisan?
