Spoilers: Character background and campaign identity.

The wandering challenger
Wulfrik’s strength and skill serve an unending obligation to the Ruinous Powers. He must seek out formidable champions and face them in combat, whether his quarry is mortal, undead or daemonic. The next challenge carries him beyond the boundaries of a settled kingdom.
His warriors share those journeys, raiding as they follow him across the world. That makes the warband central to his identity: the famous challenger travels with followers who fight beside him, rather than wandering entirely alone.
Seafang and the campaign
Seafang is Wulfrik’s named ship. In Immortal Empires, his World Walkers faction turns the idea of the travelling warband into a campaign of distant expeditions. Choosing where to sail creates the campaign’s next conflict; the character’s background supplies his motive for seeking one.
The curse in the novel
C. L. Werner's Wulfrik is a Warhammer Heroes novel. The English ebook jacket puts him coming out of the mists with destruction in his wake. The Ruinous Powers have cursed him. He has to travel the Old World and take prizes that will appease Chaos. Dark forces then plot against him, and the jacket's stake is an enemy within: find that enemy, or lose his soul to the Dark Gods.
The game's roster adds a detail the English jacket does not. He has slain dragons, kings, highborn lords, and beasts of legend, and none may refuse the challenge, delivered in the quarry's own tongue. Hunter of Champions pins a character in place while he fights them. Seafang is the campaign's ship. The novel's prizes and the game's sea route are the same reputation told from two desks. A voyage in Immortal Empires does not complete the book's search for the enemy within.
Where Update 7.0 puts the wanderer
Update 7.0 moved his start. Home is the Troll Fjord in the Vanaheim Mountains. Wulfrik himself begins away from it, at the Sea of Serpents, which the notes describe as closer to his nomadic life. The older home they name, and leave, is the Monolith of Bjorkil Bloody-Hand. That is a campaign-map change, dated with the free Norsca overhaul, not a rewrite of the curse.
Throgg, in the same update, spends Trollkind on a troll country. Sayl, from Tides of Torment, sabotages rituals and sells lies. Wulfrik remains the challenger with a ship. The Norsca pack is still the purchase that unlocks him. Archaon cannot subjugate Norsca under the Update 9.0 list.
