The basic legend
The basic legend
Who are the 13 antediluvians ?
[VtM2,p52] says that Lucian (Lasombra or Cappadocius) and Mekhet (Tzimisce or Malkav) are widely known Antediluvians. [CbR-Tz] says that Mekhet, childe of Ynosh, played "shadow games with mortals" (could this be Lasombra?).
[CbR-To] and [CbR-V] suggests that Arikel was not the toreador progenitor, and that she was killed by the Nosferatu and Setite Antediluvians, who cut out and ate her heart. The Toreador ancestor is then Ishtar/Astarte/Inanna, a bull-figher, that fought with the Gangrel Antediluvian and took shelter with King Minos, siring his son, who fell to the beast and became the Minotaur of mythology.
Namrael the Enochian is described in [MC]. She may be a progeny of Irad.
The Lhiannan bloodline [DAC] claims descendence from the Crone. If true, and if the Crone was embraced by Caine, then there would have to be a 3rd in their bloodline. The Crone is also rumored to be the "third" Baali Progenitor [Cb-Ba], this would make her 4th, which would explain how she could bloodbond Caine without being a mage.
According to the Erycies Fragments, Enoch, Zillah, Jabal, Adah, Tubal, and Mehujael are names of some of Caine's children and grand-children.
When were they embraced ?
Who sired each of them ?
The Baali bloodline is said to have been founded by three Antediluvians, but it should be by three Methuselahs.
Where were they around 2800 BC ?
What happened to them ?
People from the vampire mailing list (Fab Moicano and Andreaz Forsgren) propose this information about what the antediluvians are doing right now :
Who are the four Aralu, guarded by the True Hand ?
Who sired the Ravnos and the Gangrels ?
Firstly, I believe that Ravnos, as referred to in CbR, is Dracian, of the second generation. It says in CbR that Ravnos was embraced by Caine (Kaen) himself, and that he then embraced Ennoia, who is 3rd gen. Ennoia is Deanna, the mother of all gypsies (from WoD Gypsies). Given that vampires live forever and gypsies are only mortal, the stories are going to diverge a bit over time. Sarrath must have been her son, not her brother (as in WoD Gypsies), because Ennoia was the mother of the Garou as well as the gypsies (CbG). And Ravnos' uncle was a Silent Strider (Children of Sarrath) who founded the Lupinos gypsy family, and as gypsies they were all descended from Ennoia/Deanna.
According to CbG, Ennoia had a vampire lover who embraced her. According to CbR that was Ravnos. According to WoD Gypsies, it was Dracian who was her lover, but he never embraced her. Now two versions against one says he actually did embrace her, and the gypsies just don't acknowledge or remember that. Although the gypsies do acknowledge Deanna lived well beyond the normal human lifespan. Ok, so now I think we've establishd that Ennoia is Deanna.
Now, onto Ravnos/Dracian. The new Storyteller's Handbook says the Ravnos are descended from Dracian. Now Dracian was Second Generation, that much is pretty certain. The boy "Ravnos" referred to in WoD Gypsies must have been one of Dracian's 3rd generation childer (another being Ennoia/Deanna, and it is unknown whether there were others, but CbR says that Ravnos (Dracian in this case) sired many times, so there may be a number of Ravnos antediluvians, but that's another debate entirely). So Ravnos from CbR is Dracian from WoD Gypsies, and "Ravnos" from WoD Gypsies is probably Ravana who was destroyed in Bangladesh, or possibly another 3rd generation Ravnos, if there are any others who have survived this long, or if there were any others at all.
Also, according to the Erycies Fragments, there were 6 of the Second Generation (the other 3, to my best guess, being Ravnos/Dracian, and the King and Queen of Nod, whom Haqim killed, and with whose blood he embraced himself). Also, in the prophesy of Ravana's death, it refers to the Wanderer, third Childe of Caine, whose descendants destroyed themselves in madness.
So, to conclude, Ravnos was Dracian, of the 2nd generation, he embraced his lover, Ennoia, aka Deanna, mother of the Garou and the gypsies. He also embraced Ravana, and possibly others. Ennoia was of the Ravnos Clan until Caine cast her out for orchestrating Ravnos/Dracian's (although according to WoD Gypsies she was not involved) death at the hands of the rest of the third generation, who ruled the Second City. She then founded Clan Gangrel.
