Tide of Change
High Overlord Hzayeth
Noone remembers how the overlord looks like any more. But his name inspire fear and many tales change his appearance and nature. In offical documents it is known that he was powerful enough to cow entire warbands of chaos heretics and space marines with a demand. He fough the saint Solar Macharius and seems to have lost the battle ( least to imperial decree)
He is known as the High overlord as he commanded a fleet of such magnitude it easily destroyed the first fleet of the Calixis sector. His name is the tales of fear to scare liddle children to not stray from the emperors light. And in the darkness cultists praise his name and his return from beyond the Screaming vortex.
