An awful idea. I will have no part in any 9th edition where this travesty is canon.Update from /tg/. The Norscan idea has been developed a little more. A warrior along the lines of Beowulf, who makes himself known by defeating some mighty chaos beast and saving/freeing/reclaiming a city in the east. Theoderic Gausser or Valmir von Raukov "appoint" him Elector-Count of one of the eastern provinces in hopes of giving themselves another ally in the form of a Norscan warlord at the head of a mighty, northern band. One suggestion was that the warlord turned from his Chaotic masters after seeing Archaon fall at the hands of Valten. The point being that he wasn't a Chosen, but a Norscan that was part of the marauding horde, following Archaon because he was the biggest, baddest warrior around, and once Archaon was put down by Valten, looking all Barbarian-God King with Ghal Maraz, he and his men have pledged himself to a near-Sigmarite cult venerating Valten and abandoning the Chaos Gods who failed to claim the realms of men.
The Norscan returns to his home in the north to spread tale of the Man who defeated the Chosen of the Gods; someone truly worthy of reverence, and leads a migration of local townships willing to abandon their homes and the gods to carve out a home in Ostland. Landing near Salkalten, the survivors of Ostland have retreated to ruined city that was once the northern jewel of the eastern province, but are unwilling to treat with the Norscans, their ancestral enemies. Our Beowulf-Warlord, with his own Hrunting (Beowulf's runesword -- possibly a runefang taken from one of the fallen Elector-Counts of the End Times?), goes off to prove his worth by hunting a mighty Chaos Troll or Dragon Ogre that arrived in the wake of Archaon's invasion but never left (our very own Grendel). Upon returning with the creature's head, he earns the keep of himself and his people, and becomes leader of Salkalten's garrison, eventually carving out his own Earldom in Ostland, to later be noticed by one of the western, Imperial Elector-Counts.
Could be that Gausser or Raukov is appointing local warlords in all of the "abandoned provinces," in looking for allies. Maybe a Kislevite boyar in Ostermark, and a halfling from the Moot in Stirland.
