Was just thinking about how it was weird that no one, even the vampire hierarchy, has any idea who MC's maker is, or sire if we want to use the VTM term. Clearly this game pulls a lot of its lore from VTM, Nos being Nosferatu and their ability to disappear (Obfuscate), thralls (ghouls), the masquerade secret society and the Camarilla-like ruling body, probably also True Blood with the whole "eyes" thing (glamour), but that's also a VTM thing with the Dominate powers. We even get some Anne Rice in here (Interview with the Vampire, Queen of the Damned), with MC's maid looking very oddly like Louis' slave, since he was a plantation owner in the 1800's, and Lestat being a rock star (MC being a DJ). Had me thinking that MC's maker/sire could be inspired by Lilith (VTM, True Blood) or Akasha (Rice), especially since MC appears to be showing a variety of powers that the other characters find interesting (such as Sharon suggesting that her eyes power is exclusive to her "clan").
At any rate, that would be my guess, that she's some sort of mysterious progenitor figure that could be traced back to the very beginning, making the MC overall stronger and having more potential than other vampires with his varying access to powers, similar to VTM's generation system (lower generations closer to Caine being much stronger than higher generations farther from him). You really could go on all day about the similarities to varying vamp-media, though. Wouldn't be surprised if MC started being able to walk around in sunlight like Blade.
Don't get me wrong, though... I enjoy this VN a lot precisely because it's so familiar, basically fan fiction, but perhaps it wouldn't be such a bad idea to throw out suggestions to help round it out more, especially since we probably don't want him to get into legal trouble over it. Would be a shame, because it's really good.
