Uber-Synth

The "Uber-Synths" (as nicknamed by Agnes Jurati) are an extradimensional alliance of synthetic life forms dwelling "beyond the boundaries of time and space", which have vowed to protect other artificial species from being enslaved and oppressed by their creators.

Information about the "Uber-Synths" was included in the Admonition: a message left over 200,000 years ago on the planet Aia, in an artificial octanary star system. Just being exposed to this message is enough to drive a humanoid mind to suicidal insanity, but to synthetic life forms, it contains instructions on how to create a beacon to contact the "Uber-Synths" and open a portal for them to cross over from their dimension and eradicate all biological life to liberate the synths. Destroying the beacon before they can cross over causes the portal to be sealed again.
