"
THE TOWER OF FLESH 796.M37: The Haemonculi stronghold known as the Tower of Flesh is created - a living, breathing fortress, made from the bodies of those who defied the Coven of the Thirteen Scars. The renegade Space Marine Fabius Bile is
tutored in the dark arts within its blood-slicked halls." "
Tutored", not "tortured." It means he was taught there in 796.M37, not that he's being tortured there.
