Just an idea I had, wanted to see if it were worth developing.
What if there were anomalous object (group, species, faction, etc.) that were both sentient and intelligent and engaged in a (war, feud, dispute) with another anomalous whatever it may be?
Say the first anomalous object becomes aware or is aware of the Foundation and their purpose and through some means of communication manages to make the Foundation aware of the presence of its enemy or their devices without giving up themselves. In this way, first anomalous object(s) know that they can use the Foundation's resources and goal of containing anomalous objects as a weapon against the other anomalous object(s) to keep them contained or at least give them a war to fight on two fronts.
Has anything like it been done?
