I'm thinking of playing a Vampire of the Masquerade game and I'm very much thinking of having the two main NPCs that the players interact with be of the Toreador Clan.

In this case the first one is a 380 year old Vampire with a humanity rating of 6. The second one is a 150 year old Vampire with a humanity of 7.

So pretty high humanity for their ages. I haven't written any more more about them yet but I would appreciate everyone pointing me in the right direction for this.

For such two vampires, what are some things to keep in mind when interacting with other vampires, within their clans and outside it, and mortals?
