Lore: Vampire covers the general racial information - not information that is specific to a sect, but information that is general to the race as a whole - disciplines, names, general history, medical and physiological and psychological details. Obviously, the higher your lore, the more you know.
You have begun to learn some truths - the vampiric community has begun to take shape before you. Not merely Bram Stoker's villian any more, you have heard some names and been given some context and definition for them, be they clans or disciplines or sects. You have begun to grasp vague details of physiological nature. A little knowledge is a dangerous thing. More details have come to you - expansion on the knowledge already gained, and further on the politics and struggles that mark the vampiric community. You could talk with a member of the group in question without a disadvantage - you have learned stereotypes and 'buzzwords', you can list some of the nicknames and use some of the slang. You've learned things you wish you never had, ranging from historical involvement in situations you never thought connected to the nitty-gritty of disciplines common and esoteric. You know the subjects at least as well as they know themselves; in some cases, you know more than they. This could well be terminally dangerous.
