Grimgroth is a hawk nosed elderly white male. He wears stereotypical "wizardly" robes and slicks back his long black hair.
Grimgroth is not one of the original members of the Council of Seven, having been elevated to replace the rogue Goratrix; this promotion was sponsored by Grimgroth's own sire, the Tremere founder himself. He habitually changes the location of his chantry very often, but at the moment his prime chantry is in Rome
Like all Tremere Councilors, Grimgroth is responsible for furthering his Clan's interests in a broad geographical area. Originally, his territory was France; in the modern nights, he has been given responsibility for the entirety of Western Europe, including the British Isles and Australia.
Many rumors surround this figure, some say he cooperates with the mages of Rome to bring some sinister fate for all Europe, other came up with the possibility of Sabbat ties, to an extent that even implicate him as a spy for Goratrix. However, few facts are known for sure.
