The FBI's Unusual Incidents Unit is the primary domestic paranormal agency of the United States, tasked by the Domestic Security Council with enforcing paratech regulations and upholding the Veil. Due to a limit of means and jurisdiction, the UIU largely focuses on investigating paranormal crimes and covering-up anomalous incidents. One of their most important functions is policing the numerous pocket universes within the US, which act as enclaves for the paranormal community.
