Grot Week, Cogfort Lore, and a Fresh Rumour Engine Keep Warhammer Buzzing

Games Workshop put out a nice little mixed bag of hobby news here. So, this set of updates is less about one giant reveal.

Instead, it builds momentum across several fronts at once. You get another sneaky look at the new Gretchin, a proper lore dive on the long-teased Cogfort, and one more Rumour Engine image to spark arguments in every group chat.

Another Grot steps out of the shadows with loot on the brain

Day 2 of Grot Week keeps the joke going, but it also sells the new kit well. Yesterday’s Grot looked braced and ready to shoot. However, this one is doing what Grots arguably do best, sneaking across the battlefield and clearly eyeing up somebody else’s stuff. That detail matters, because it gives the model a lot of personality. So, the reveal is small, but it feels very on brand. It also keeps feeding into the Friday Armageddon unboxing, where the full boxed set will finally be shown off.

The Cities of Sigmar finally get a walking fortress worthy of the wait

The Cogfort piece is the real centerpiece here, because it finally explains one of those long-mentioned Cities of Sigmar oddities.

Detailed Warhammer siege-tower model named 'Stonewarden': a stone-arched tower on mechanical legs, with cannons, figures manning weapons, banners, and a rocky, grassy base.

A Cogfort is basically a mobile castle, powered by pistons, gears, emberstone, and a frankly absurd amount of industrial faith. It belongs to the Ironweld, and it exists to batter through sieges and terrify everything in front of it. Better still, the article confirms two main patterns. The Cannonade Cogfort is the ranged monster, packing the godbreaker cannon with ammunition types like cannonballs, runic shot, and grapeshot.

Meanwhile, the Conqueror Cogfort trades that for a realmscorcher flame cannon and an assault ramp, so troops like Steelhelms and Fusiliers can charge out after the target area is roasted. The article also adds some great nuts-and-bolts lore. The pilot, or puppeteer, works chains to move the limbs, while the tendon-chains on the legs serve as a notorious weak point.

Most interestingly, the emberstone-fuelled arco-combustor engine is mounted to a dirigible, so it might be recovered even if the Cogfort itself is destroyed. That is exactly the kind of overbuilt nonsense Cities of Sigmar needed.

A new set of fangs sends the Rumour Engine back to work

The latest Rumour Engine is much shorter, but it does its job. After a brief break, the feature returns with a close-up of a snarling mouth, complete with a strong jawline, oversized fangs, and a long tongue. So, the hook is obvious. It is just enough detail to look familiar, but not enough to lock down. That usually means a week of people confidently guessing five different systems at once. Taken together, these updates do a good job of covering the whole Warhammer hobby cycle. You get model teases, world-building, and a fresh mystery image to chew on.
