Karel Mach
Karel Mach was a Clan-Father of the Iron Hands Legion's Clan Raukaan, who survived the Dropsite Massacre during the Horus Heresy. After escaping from Isstvan V, he formed a Clan Council along four other surviving Clan-Fathers to lead the Iron Hands in the aftermath of Ferrus Manus' death.[1]
Karel Mach was killed along with the rest of the Clan Council in an ambush shortly after the formation, leading to Shadrak Meduson taking over leadership of The Shattered Legions.[1]
