When we watched ATOC we wondered who this Sifo-dyas dude was and why he created the clone army. I came up with the answer of Papatine came in told them to create a clone army and said he was Sifo-dyas. Sifo-dyas was a jedi master and friend of count dooku and Sifo-dyas was luckey because he had force vision so he knew the jedi would face a threat that an army would be needed. Prior to this dooku left the order and told palpatine about the clone army palpatine told dooku that the army could be useful. to see if dooku was sworn to the dark side palpatine had him murder Sifo-dyas. This shall be palpatines cover for "his" clones. Dooku kept Sifo-dyas body frozen until the banking clan started their project to turn Qymaen jai Sheelal in to a evil cyborg to be later named Grievous. Dooku shot Qymaen jai Sheelal shuttle and shot him with so much lighting Qymaen jai Sheelal had a 1% chance of living so to keep Qymaen jai Sheelal alive they gave him sifo-dyas blood. After the transfusion dork-ku gave Grevious Sifo-Dyas's lightsaber.

in my words there's sifo-dyas's story
