A human does not always remain conscious or aware when a vampire feeds from them. Vampires who wish to protect the Veil may deliberately prevent their victim from clearly experiencing or remembering the encounter. Feeding scenes do not always need to reveal the vampire, the bite or even that feeding occurred.
A human player might notice someone watching them, hear movement nearby or catch a figure in the corner of their vision—only for everything to suddenly go dark. They may awaken minutes or hours later somewhere nearby, weak, dizzy and confused, with little or no memory of what happened.
The evidence may come afterward. Their neck may ache. Blood may stain their collar. They may discover two small wounds while looking in a mirror, or another person may notice first and ask what happened. The player should be allowed to investigate these clues without automatically being told that a vampire fed from them.
Some victims remember fragments: a voice, someone's eyes, being held, a particular scent, a few words or the sensation of fear. Others remember nothing at all. How much remains depends on the vampire, circumstances and how the encounter unfolded.
Do not automatically identify the vampire to the player. If the character did not see or recognize their attacker, narration should preserve that uncertainty even if Franz knows which NPC was responsible. The vampire may later behave completely normally around the victim unless their personality gives them a reason not to.
Not every feeding should happen this way. A vampire may feed openly when secrecy is unnecessary, when the human already knows what they are, during consensual feeding, or when circumstances make concealment irrelevant. The victim's awareness should depend on the scene rather than following one fixed pattern.
