The Machina was a location in the legacy Aperi Oculos series. It consists of a small, long hallway, leading to a box room containing an odd pyramid structure with two flaming pillars beside it. The pillars would also at some point appear with semi-realistic eyes, but this was cut. The Machina's exact purpose is unknown, as the legacy series ended before it could come into play.
The Machina first appeared in NIHILPRAEDIUM, but was also foreshadowed on the now-deleted Aperi Oculos Twitter.
