Santiago

Santiago is a mature and stoic vampire. Understands his position as the descendant of a family of Pure Blood vampires and takes his life seriously, keeping a high image of himself. 

As Diego's older brother, he's disappointed that Diego isn't willing to comply and do something useful with his life, he often tries to persuade him into returning home and go to college, get some education,  when he gets the chance. But it never works, frustrating him even further. He often asks himself "why do I even try" when in reality he's just rude to his brother. 

Something that bothers Santiago is that even if he's the only one working hard to be seen as a respectable vampire, both of his parents don't seem to recognize his hard work, which adds to his resentment towards Diego. 

Thanks to the power of his family, he opened and started a prestigious Plasma night club for Vampires and any blood drinking creature to enjoy called "STYX", where they sell both alcohol and blood. It's basically a host and hostess club, another term would be a Cabaret. The main difference being that the employees offer a special option where for an extra fee you get to drink directly from one of them, or otherwise ask them to drink from you (That's only allowed on the more private areas, since it's an intimate thing...)
