I'm BB and my boys are the Professor and Charles. Both are humans (a sorcerer illusionist, and a psychic cowboy), and have been around Zion for a little bit. Professor Blackstone for 11 years (joined up in 1908), and Charles for 2.
The professor isn't terribly familiar with most people since he tends to keep to his own company. Not out of rudeness...but James can get lost in his own world, quite literally given his abilities. Still he's always game to chat during meal time, or discuss (at great painstaking length) magic and his research too. Lol. Beware, he can talk on hours about it.
Charles is far more outgoing, when he's not passed out drunk or high. The gunslinger/gentleman always has a seat open for any who wish to play poker, but his rep for being unnaturally lucky has started to spread over the last year or two. So play at your own peril ;) Still if the locals ever give your character trouble, Renmont will be there with his revolvers ready to lend a hand, or a few bullets if the need arises.
