Yeah I have no idea on where this topic is going either. right now it sounds like a pile of nonsense.
The earliest novel in terms of chronological order for Fantasy I think is the Sundering, followed by the War of Vengeance, then The Rise of Nagash, Neferata followed by The Doom of Dragonback and then the Legend of Sigmar, and then Skaven Wars: The Black Plague trilogy. note that this is just my assumption due to understanding the timeline of the game.
Yeah in Masters of Stone and Steel, Barudin was willing to do more than just fuck up some Humans over a grudge,
You see an Empire noble named Vessel made a deal with Barudin's father to fight together as allies to face Greenskins attacking the moot which were near vessel's lands, The Dwarfs only agreed because they were paid with chests of treasure and because the warband of greenskins were known to the Dwarfs and had grudges placed upon them.
However, once the Greenskins showed up, Vessel and his army bailed, leaving the Dwarfs and the Half-lings to their fates, The Dwarfs won of course but they lost their king in the process, which happens only because Vessel bailed like a coward.
So Vessel was not only an oathbreaker ( which is the worst conceivable thing in creation to them), but he also got their king slain due to his cowardice. So a grudge was written by Barudin to take the life of Vessel for this offense, However the King had his own grudges that had to be struck out by Barudin before he could pursue his own or else the ancestors won't allow him into their halls due to the shame of lost honor.
Also Barudin also couldn't simply stop managing the day to day affairs of the Kingdom he inherited and he also had to fend off attacks by Skaven and other enemies. Which took up the vast majority of his time.
So by the time Barudin found the time to strike out his grudge, Vessel had long since died and his grandson who by the way had no knowledge on his grandfather's sins inherited the grudge debt, which is death.
He obviously tried to parley with the Dwarfs to spare his life but the Dwarfs didn't care and replied to the messenger who spoke on his lord's behalf for him to come out and die or they will lay waste to the city, killing everyone inside, man, woman, child, healthy, ill, innocent or guilty.
All would die because the descendant of the man whom the grudge was written over was in control of the city and wouldn't come out to face execution over his grandfathers' sin of breaking an oath to the same Dwarfs.
So don't ever screw over a Dwarf! or else!
Never trust elves, even more so their petty Gods who are even more full of themselves than War of the Beard era High Elves.
When you say people appearing in the Warhammer World, what sort of people do you mean? People from our world? People from the future during the time of Age of Sigmar? and will these people have anything that makes them useful or at least able to even survive in the Warhammer World? Also are these people original characters? or will they be self-inserts disguised as original characters since that trope is all too common with fanfiction sadly.
The geography of the Warhammer world has no connection to our world other than coincidental landmass shape and positions that are only somewhat similar to our own. But other than that, the Warhammer world is its own world within its own universe, or should I say, WAS, since you know, end times and all.
And before the old ones found it, the planet was a literal snowball covered in planet-wide ice, snow, and small patches of tundra. Filled with dragons of truly monstrous size, fimir and other creatures that love that sort of climate.
The Old ones had to use their Techno-sorcery that was almost god-like to move the planet closer to its sun into a new orbit in order to melt the planet-wide ice and snow so the planet is more conductive to life other than the most hardy of creatures who thrive in such extremes.
Its also why you hardly see any dragons in the lore, since the warming climate put them all to sleep other than smaller ones that the elves use.
The future of our Planet will be one of Fire, not ice, due to the sun eventually growing so hot that it turns the planet into a desert and kills off all life, and then it will get so big that it will engulf the planet and melt it down.
