No new gameplay yet, but Clan Introduction videos are coming out:
First off, Thinbloods:
Thinbloods are Vampires so far removed in genalogy of the Kindred from the powerful 13 Antedeluvians that some are barely Vampires at all. Most Thinbloods go through their existence never knowing their Sire or finding their place in Kindred society, as without the distinct traits of Clan they have no leads to start looking and no one who feels any obligation towards them.
That doesn't mean Thinbloods are powerless, only that they will have struggle harder - and without a worn path they are free to develop themselves.
The powerset advertised for the Thinbloods is based around common vampire horror tropes - Bats, Telekensis and Mist.
Second arrival are the Brujah:
The Brujah are a Clan descended from one of the 13 Antedeluvians. The older Vampires of the Clan tend to be radical thinkers, aggiators and facilitators of societial change - the younger ones, however, feel the call within their blood more strongly and are quick to action, even quicker to anger. The Brujah tend to feel drawn to the outcast and the oppressed but also to those who see themselves unbound from society; they recruit their fledgelings from those who would see the order of things toppled and/or fight for a better tomorrow.
The powerset advertised for the Brujah is based on close combat - with powers that enhance your blows and speed.
Hidden Text: OT Note Show
I was wondering when they were going to approach the Brujah in the marketing, considering one of the places the controversy mentioned in opening post got started was with the notes for creation of Brujah characters. Not doing the Brujah was kinda always out of the question as they tend to lend themselves well to characters that give players an easy "in-between" space, regardless if the clan is employed for PCs or NPCs.
