Artemius Grohm is an Interrogator-Chaplain of the Dark Angels.

He chased the renegade and The Fallen Borroleth onCordassa. During his operation on this planet, he repeatedly thought about killing the Inquisitor Mattius Heiron, if the inquisitor should get wise to the Dark Angels.

Finally he killed Borroleth, as he offered the inquisitor to disclose the secret or the Dark Angels. But therefore Artemius Grohm could not convert him and consequentially not discover another renegades.

Artemius is wearing two black pearls on his rosarius meaning he had converted two Fallen ones.
