So I got this bad boy done, and I'm pretty happy with him, definitely fits as one of those "Oh S#%t" HQ models. He is absolutely huge, though he'll just be a Thunderwolf Lord for now (until Legions comes out at least).
Jarl the Gutsman, Blood Sorcerer of Nurgle, Pledged to the World Eater Lord Hans Kho'ren
While it is true that almost every single Brother of the World Eaters Legion pledged himself to Khorne during the Heresy, their are exceptions to every rule. Exceptions such as the Gutsman. Like all World Eaters, even before the Heresy, Jarl was enthralled with killing in the most savage ways. But it was truly mortality that interested the young Brother the most. And as he studied he came upon Nurgle, who whispered in his ear. And so when the World Eaters fell upon Holy Terra, Nurgle bestowed his gifts upon Brother Jarl, showing him his enemies death in their blood. From then on he was not just Jarl, he was the Gutsman. Though no longer fully trusted by his Legion brothers, Jarl proved useful as an ally. On Skalathrax, as the Legion scattered, the Gutsman joined forces with a Captain named Hans Kho'ren. Ever since then they have marched against the Imperium together. During the First War for Armageddon, while most of the hoard marched through the jungles toward Armageddon Secundus, Jarl stayed on Prime, in Hive Death Mire. While at Death Mire the Gutsman sacrificed the blood of thousands in practicing his dark arts, and forged the daemon weapon Patroclus.
The Gutsman carries the Daemonic stave Patroclus.
The plastic Nurgle Chaos Lord is just a pleasure to work with. Great molding, minimal lines, it's just awesome that it is a plastic kit. And as far as characters go, it's super cheap!
