Unit Four was created at the same time as the Special Investigations department, and widely regarded as unlucky for its name – Four, or “Shi” in Yamataian, means “Death”. Quickly it became a dead-end post, where screw-ups, politically unsavvy, and eccentrics were sent to serve the rest of their years in the
YNP. Unit Four was destroyed in Malifar during
Battle of Yamatai. It was reconstructed in early
YE 34. Agent Araiah, an
NH-29 and veteran of the
First Mishhuvurthyar War, took the reigns of Unit Four.
