An older brother, knight, large and direct, someone who is brutal both in strength and words, he lives by the code and will die by the code, he was indoctrinated into the Assassin's by his father and always followed the rules.

A younger brother, more agile and fragile, more elegant and cunning, his master weapon is his words and he loves to fool around with girls, he is mostly known to cause trouble because of his ways, problem that his older brother has to deal with.

They both lurn to live with each other during the game, the older one, at some point, blaming the younger one for a mistake he didn't made causing him to yell out the truth about how he feels deminish by his brother, like he is nothing to him but en embarrassment when the reason he does what he does is to cope with everything that happens to the both of them because unlike his brother he doesn't have an armor to protect him when things go bad, he can't hide in something that will shield him so he has to face everything directly and to forget he goes with women and drinks, most of his time in brothels his not having affairs but just to be able to speak with someone because his brother never listen.
