The Admiral in charge of the entirety of Fleet's investigative, intelligence and black ops arms. . Counterpart of the White Admiral. Currently held by a Hinichi whose other details are, pretty much appropriately, obscure.
The Night Admiral is, strangely, always a black Hinichi male with golden eyes. Probably because it's planned that way, with a roquelaure.
The current Night Admiral that Lisinthir meets in Amulet Rampant does not carry themself like a black wolf with golden eyes, leaves silvery fur on the furniture, and moves like someone wearing a mask - meets people's eyes like someone who does not fear being recognized. Is a silver furred female Pelted of unknown configuration with brown eyes under a roquelaure.
