CAUTION SPOILERS;
Raphael:
from what i gathered from the book,
He looks to be about the age of 14-15:
He's got dark curly locks, hinted to be of spanish decent,
He wears a cross necklace,
and is most often written to be wearing victorian era suits and shirts,
He's Intelligent, and apparently very handsome,
Just under his neck he's got a scar from when he was turned into a vamp,
His role in this story, really comes in at the end, when he and his clan are called upon to fight in the final battle against valentine, in exchange for simon the 'day-lighter' and a seat on the clave counsel,
I hope this helped!
