Russel Hammond is just some kid from Brazil who loves the Classic World of Darkness.
According to some accounts, Russel might be an incredibly powerful Ventrue methuselah who pretends to like role playing games just to establish a herd of nerds - and also dig for some worthy ghoul material.
Not much else is known about this character, except that he has the ability to be very (VERY) annoying sometimes.
His name was not originated from the movie "Almost Famous", as it is much older than that (45 BC, to be exact). It is spelled with only one "L". Therefore it's Russel, not Russell - thank you for your understanding.
