The Hungry Ghosts have a tendency toward elaborate basing, and the Grudge Master is no exception. In fact, the Grudge Master's base is integral for Anniversary Grudging purposes. It also takes the signature base-bits-sprawl over the edge to new levels.
As we can see, the front of MSgt Grevess's base features heads of great enemies. Prominently spiky is an Ork Nob severed head, who also shares the Hungry Ghosts' love of skull symbols (let's face it, just about everyone in the 40K universe has a skull fetish). The Orks were the last to mention the existence of the Squats in the 40K universe. Despite the enmity, the Squats must grudgingly note that minor respect in their Book of Grudges, though the mocking term "stunties" was used (White Dwarf 289 p.108, Feb 2004).
A second Great Enemy appears to the right, a severed head of a Genestealer, of the early 1990s plastic variety. The color scheme is a reversal of the Grudge Master's, a slippery blue hue pocked with red and yellow pustules.
Peeping out from the side is one of the cute little Skaven rats that come with the Hell Pit Abomination.
And another little rat on the other side. Both bear the same fiery fur that marks the beards of the Hungry Ghosts.
We can see that the severed Genestealer head has left a sticky mess on the floor. Another mess was the moulding of the teeth - no gaps between the right and left sides, just big creased mashing surfaces like wooly mammoth molars. Seems that Genestealers crush their nummies instead of tearing them apart as Imperial propaganda would have us believe.
The rats rest upon the hands of former allies, one upon the gloved hand of a Space Marine and the other on the putrid rot of an Imperial Guard meatshield. The hands of those who offer false friendship are severed like those of the thief: indeed the theft of trust can be worse than theft of gold. They are left for the vermin to do with as their dirty little minds see fit.
So too with the cast-off weapon of the enemy. The bastardized version of the lasgun given to the humans by the Squats as a welcoming gift to a dangerous galaxy points to the past, broken as the promise it symbolized.
But what can you expect from a species with such a tiny skull and tiny brain? Seriously, though, GW design team, is that a child skull? Monkey? Pixie? Khorne is not impressed.
Our Grudge Master, so fraught with symbolism already, has more symbolism to unleash. From above a carefully crafted Chaos symbol is revealed, the diagonal axes formed by severed heads paired with severed hands (and pointy rat snouts), skull embossed arrowheads upon the Grudge Master's shoulders, and lastly the barrel of the lasgun pointing behind while
Facing forward is the skull, bedecked with golden laurel wreath, dedicated to Lord Death, whose fires glow from within. Death will come to all, to some it will come soon, from the Grudge Master.
