It's not just 40k that's getting the Khorne previews from Games Workshop. Warhammer Underworlds: Nethermaze is getting its own preview as well with a look at Skullgrinder Herax. Get a look at his mini and some of his cards in this preview.
From the article:
It’s 8/8, so it’s Khorne Day here on warhammer-community.com! If you like blood, skulls, the colour red, or any combination of blood, skulls, and the colour red, we’ve got lots to show you today, starting with a member of a new Khorne warband for Warhammer Underworlds.
The Shadeborn and Skittershank’s Clawpack have had the Nethermaze to themselves for too long! Even the imminent arrival of Hexbane’s Hunters isn’t enough to satisfy Khorne – he’s sending Gorechosen of Dromm to the murky core of the Realm of Shadow to claim more skulls.
The Slaughterpriest Dromm intends to enact a blood ritual at the heart of the Nethermaze, but he can’t do it alone. He is accompanied by the Skullgrinder Herax, a creator of grim artefacts, who shows that Khorne followers aren’t all about skulls and blood – they can also like fire too.
