These devices are essentially like a bug. The Terra Era people without permission cannot modify them. In this case, rather than destroying or altering them, it is better to maintain the bug and let the ecology of this area continue to function.
But it's different with the Silverpeak Domain—they have permission!
Although the one with permission is Ian, every high-ranking member of the Silverpeak Domain holds a part of Ian, making it easy to manipulate these pre-era civilization machines.
Ian's level of access is so high that he can control about ninety percent of the pre-era civilization legacy on Terra, spaceship legacy, and part of the Spark legacy.
