Yeah, but it doesnt look like your a Gangrel, they agreed that much, Im thinking not one of the main clans, but an offshoot, the Sire was obviously old the way she mentioned the romans, sounded like she was there, so im guessing once you learn about blood potency you'll find yours is very powerful, heck in WTM 1st / 2nd Ed the ancient ones often learned other abilities just to give them an advantage finding texts, or making deals to gaine them, and if shes as old as she could be her blood might have transferred some of that potential to you...
For those that remember the early World of Darkness RPG's
Nos... No, and Gangrel highly unlikely
Capadocian / Giovanni possibly but unlikely, she could have been a survivor from the purge
Ventrue ... doubtful character isnt enough of an asshole
Tremere ... possible but since we hadnt seen signs of magic unlikely
Setite or Assimite ... possible but as mentioned in a previous post unlikely if she was as old as she seemed
Toreador ... I doubt it but as someone in the entertainment field I wouldnt put it past them
which leaves Brujah and True Brujah both possibilities, True Brujah would be nice, would fit her not giving an f* what the Archon thought.
Or one of the other clans that I can never remember, or many of the offshoot clans possible
Im guessing she was an offshoot clan to be honest, the mention of a pact to have the claws or not, taking it then and there makes me think one of the darker ones.
But we will see once the Devs gets there, as some have said the similarity may be as far as the dev takes it.
