Sarthos
Sarthos was the Cardinal of his Homeworld Nicodemus and a member of its noble House Matheldas. He would aid Inquisitor Lord Defay and his acolyte Gravier in their investigation of the Chaos taint infecting Nicodemus, which eventually led back to House Matheldas itself. The House would be destroyed by their hands, but when Defay discovered Sarthos was related to Matheldas' corrupted bloodline, the Inquisitor Lord and Gravier killed the Heretic Cardinal. It was revealed however, that Sarthos had long ago been possessed by a Daemon, which immediately attacked them. It was only destroyed by the use of Defay's psychic powers, but he felt tainted afterwards and fled from Nicodemus[1a]. It was later discovered that the Daemon's attack began Defay's own fall to Heresy.[1b]
