User:Saberstorm/Forerunner Extrasensory Infiltrator

A small biotech device, the Extrasensory Infiltrator was designed by the Forrunners and used in their campain against the Flood.

Description
The device itself is small, barely 5 cm long and 2 cm wide, and resembles a crystalized incect fossil. It is biokeyed to be activated by the touch of Forrunner skin, and Human as well, so wearing gloves is imperitive while handling them. They are a white, glassy crystal when inactive, and glow electric blue when activated. Upon activation, the device will burrow into the host body, liquidize, and then mold itself to the vertebrae directly beneath the skull. It then absorbs and conforms to the host's DNA, becoming indetectable to medical scans and searches, unless one knows exactly what to look for.

Function
The Extrasensory Infiltrator was created as part of the Forrunner's millitary countermeasures against the Flood. Based of the Flood itself, Forrunners who had the device implanted could hear the intent of the Flood's collective mind from a certian range. They could literally hear the Flood's telepathic commands, and then prepare appropriate countermeasures. Combined with Mercidant Bias, the Forrunners stood a good chance at continuing to counter the Flood's advance. Unfortunately, Mercidant Bias took that knowledge with him when he betrayed the Forrunners, and the Flood made it an objective to capture as many Forrunners with the Extrasensory Infiltrators as possible. Without those advantages, the Forrunner defence against the Flood faltered, and eventually failed.

Legacy
The biotech devices would later prove to be invaluable to the UNSC. Spartan 020 Sara would eventually find one, causing it to be implanted into her system. The Infiltrator would become one of the key reasons why she was able to sucessfully resist and survive Flood infection. The UNSC would later uncover an entire storage bay of the devices in a set of buirred Forrunner ruins, giving them a much needed edge in their own battle against the Flood.
