Eastern Yharnam, Hunter's clinic, back room
Victor accepted the key when Nigel handed it to him, although he did so muttering the words “But it's just a key...” under his breath, confused as to how “versed with the situation” one would need to be to figure out how to put a key in a lock and turn it. He pocketed it immediately despite his confusion, though, and his left hand – which he had received the key in – wasted no time going back to hovering next to his left hip, where his blunderbuss hang.
The Messenger reacted eagerly when Nigel reached out to pat it on the head, seeming to somehow be able to intuit his intentions and lean its head toward his hand like a pet eager to receive its master's caress. Rather than actually pat it, however, Nigel's hand met no resistance and simply passed right through the Messenger's head and body. The Messenger's excitement with the gesture did not seem diminished by this, as it clapped its hands happily while the other nearby Messengers stopped what they were doing to (presumably) glare enviously at their kinsman.
Opening the cabinet revealed that it, as had been hinted by its weight, was mostly empty, but not entirely. Various strange metal rods of various lengths, most of which had at least one hollow end, seemed like they could probably be assembled into a bigger contraption of some kind. There were also two coiled-up lengths of flexible tube and two empty bottles, and some scissors, but most of the shelf-space in the cabinet was empty and slightly scuffed-looking, as if objects had been cleared from it in a hurry. Looking at it more closely, however, Nigel did notice that at the back of one of the shelves, tugged away behind the two larger, empty bottles, was a small rack of vials filled with red liquid: three blood vials.
“The Cathedral Ward is the center of Yharnam, the district around the Grand Cathedral,” Victor shrugged when Nigel asked his question. “It's the heart of the Heal-... or, well, the white Healing Church, and is under its direct control and protection; no beasts are getting in there. It's also the headquarters of us Hunters of the White Church. You...” He paused, lost in thought for a moment before he continued: “Well, normally we get briefed by the First Hunter, but since you're special and all that... maybe Vicar Harold will want to see you?” He shrugged again. He was, after all, just a lowly Hunter.
