Sephorith kills President Shinra, powerful man with money, people under him and of course Jenova. Silver Haired Men not as mature as Sephorith but are just merely messing with Rufus (if it IS him) because they think they're so cool...trying to get Jenova's head. (WHEREVER IT MAY BE?! HONESTLY WHERE DID IT GO???)....I still don't understand their full objective. Kinda glad too, cuz that's a spoiler that will probably never be solved.
