The aperion, as detailed by Darth Plagueis, represented the component of the Force that integrated and encompassed all matter, bestowing upon it both form and unity. It incorporated elements such as gravity and electromagnetism, while also extending to encompass all of space and time. A multitude of abilities related to the Unifying Force were connected to the aperion. While not absolutely essential for generating and controlling life, midi-chlorians still utilized it as a conduit.
The "aperion" concept draws inspiration from the Ancient Greek word ἄπειρον (apeiron), signifying "unbounded" or "limitless." This apeiron played a pivotal role in the cosmological framework developed by the Greek thinker Anaximander.
