I just finished 6th Edition Tomb Kings and it was honestly highly informative. It contained a lot of details that wasn't in 8th Edition Tomb Kings and it was neat to see the development of the Tomb Kings with time. For example, the way that Nehekharan magic worked was completely different, but that's just how 6th Edition was. 8th Edition standardised all magic to follow a single uniform system for simplicity and likely for balance, but 6th Edition had all kinds of unique magic systems for stuff like Nehekhara and the Ogre's Gut Magic.
It also created an odd scenario. Tomb Kings technically aren't supposed to cast spells, only the Liche Priests do that (Settra is an exception for obvious reasons and Karitamen explicitly broke the rules to do that, so did Nagash), yet "My Will Be Done" let them cast one of two incantations every turn. Also, it's very surprising looking at 6th Edition Settra vs 8th Edition Settra, in that they seriously nerfed his magic power. In 8th Edition he's a Level 1 Wizard, but in 6th Edition he's the strongest Caster of the Lore of Nehekhara, stronger than the average High Priest (Khatep wasn't playable to be fair). The downside is that he took 2 Lord slots and wouldn't allow you to field any other Liche Priests because he hated them.
Another weird thing is that in 2nd Edition WFRP Night's Dark Masters, which was published after 6th Edition, it says that Neferata resorted to learning Necromancy from W'Soran because Nehekharan society didn't allow women to practice magic and become Liche Priests. Yet there's an Arcane Item in 6th Edition called Neferra's Plaques of Mighty Incantations that was made by the High Priestess to King Khutef (one of the Kings of Khemri) called Neferra. I suppose that can be solved with the assumption that Lahmia in particular was sexist, because it was Neferata's father who laughed at her when she said she wanted to be a Wizard.
Anyway, final note:
He smiles, seemingly amused. "Ever been to the Imperial Museum?"
You frown. "The Magnus Museum? Or the ruined one?"
"Neither, the one at the Collegium Historica at the University."
I've been wondering for a while what ruined musuem Mathilde was referring to here. 6th Edition Tomb Kings mentions the Magnus Museum in Altdorf, which in 2499 decides to stupidly display the sarcophagus of a 5 year old Tomb King named Kaspeh. Tome of Salvation mentions an "Imperial Museum in Altdorf" which displays the Obernarn Stone, which Horstmann clarifies is in the Collegium Historica in the University of Altdorf.
I assume whatever this ruined musuem is, it was probably trashed because it was displaying something Tomb King related. It's almost comical how people never learn the crucial lesson of not messing with the Tomb King's stuff.
@Boney If you pulled the ruined museum from some source, mind telling me what it is? Or is that an original thing?
