Oculus System

The Oculus System is a prototype device that interacts with Nocturne Argentum's prosthetic eye. It is implanted into the side of his head, and when activated, resembles a free-floating eye patch.

Appearance
The Oculus System is a single retractable eyepiece resembling an eye patch. It is made of smooth black metal with a machined, angular look. A small optic is situated at the bottom right of the System, glowing when in use.

The optic changes color based on function. In regular use, it glows blue. In night-vision mode, the optic glows green, and in infrared mode, it glows red.

When de-activated, the Oculus System leaves a comma-shaped piece of black metal permanently embedded into Nocturne's temple.

Specifications
When activated, the Oculus System forms a neurological connection with Nocturne's prosthetic eye and his brain. A Heads-Up Display (HUD) is projected into his prosthetic, seamlessly integrating into his vision. The System performs a myriad of duties that enhance his sense of sight.

The Oculus System comes with a night vision device that allows for Nocturne to be able to see in the dead of night using light amplification and other sophisticated technologies. In complete and total darkness, however, the System automatically switches over to an infrared device. Combined together, they form a night-vision/infrared (NVIR) device.

As a prototype, the Oculus System is equipped with a state-of-the-art marking system, able to detect humanoid objects and mark them on Nocturne's HUD. Only just out of the development phase, an alpha-stage real-time three-dimensional mapping (RT3DM) system also allows for those marked objects to be remembered and to be seen through objects.

The Oculus System also comes with a binocular function that is able to go up to a 3× zoom. Other functionalities come included, such as a biometric scanner capable of detecting heart rates and Aura levels.

Drawbacks
Even with such advances in technology, the Oculus System still has to run on a Dust battery, which only lasts about one hour of sustained use. It has to be regularly charged, so Nocturne sometimes travels with spare batteries that can replace a dead one if needed.

The System is also very susceptible to electromagnetic interference. An electromagnetic pulse can easily take it out of commission, forcing Nocturne to have to reboot it and run diagnostics before using it again.
