Samira definitely points out the interesting things about Sani Sabik RP and it's a shame that CCP focus more on SPACE VAMPIRES!!!!!!!
It also made me think about Serpentis RP. Currently I am not really sure what to chase with a Serpentis character but I think they have one major thing in common with the Sanist: Power. Initially the story about the Serpentis builds on Vengeance, but vengeance alone can't really support a whole faction and currently it feels like the goal of a Serpentis character would in some way be similar to a Sanist character. But this is also where the similarities ends as a Sanist will seek power through religion, intrigues, violence, and so on. While a Serpentis character would probably focus more on technology, economy, and status. After all the Serpentis has a meritocracy structure similar to the Caldari.
Sorry for being a bit off topic, this could probably be a thread for itself but at the same time there are some similarities.
