Grig Griez was a crimelord within the Draconis Combine who acted as a middle-man for Matabushi Incorporated during their Operation Inroad, around the year 3024. He was also well informed about the Dark Wing, and was able to identify their crest to Gideon Braver. Subsequently, he employed Gideon Braver as a courier to "Brown", one of his agents on Dustball. Brown had orders to kill Gideon Braver but the delivery turned out to be a poisonous agent to kill Brown in turn. Upon realizing this, Brown tipped Gideon Braver off to Kangaroo Jack's JumpShip, the Stone Arrow, instead of killing him.
The Draconis Combine's Ministry of Peaceful Order and Honor on Galedon V levied a bounty of 200,000 C-Bills against Grig Griez in 3024 for his numerous crimes of murder, rapine, destruction of personal property, arson, grand theft, assault of Draconis government officials, counterfeiting, forgery, piracy, and others.
Griez was described as a bloated man with merciless black eyes and a thick and sinister voice. Alledgedly operating from an uncharted periphery world beyond Land's End (which, if it actually existed, might be the same world that later became known as Rezak's Hole), he could be found in a secret underground base outside a major city on a Draconis Combine world; the scenery there was reminiscent of an ancient Arabian Nights holovid.
Grig Griez appears in the MechWarrior computer game. The game and its storyline are apocryphal (see section about Canonicity in that article); they are expressly not included among the list of canonical sources for the BattleTech universe. However, it has also been said that information from certain sources namely including this particular game can be assumed to be part of the shared universe if it makes sense, until contradicted. MechWarrior in particular is one of the computer games where the storyline is widely treated as canonical.
- The exact world on which Grig Griez's base is located is randomized among several worlds in the game; typical locations include Delacruz, Tabayama and New Samarkand.
- It is possible for the player (as Gideon Braver) to collect the bounty on his head after killing Griez later on in the game, but re-visiting (and then killing) him is not required to successfully finish the game; Griez's death at the hands of Gideon Braver is therefore unconfirmed.
