So I decided to make a bit of a structired argument on the reasons to Read the Libber Mortis
On the Liber Mortis
Why we should never wield Necromancy (no not even then): Necromancy would make us loathed by all sane thinking beings, it would damage Mathilde's sanity in becoming the monsters she has fought so hard against and who killed Van Hall. If the Empire itself were dying and could only be saved though the use of necromancy than the Empire should die. That which is 'saved' by necromancy, be it a loved one a land or anything else is a monstrosity that is better off not existing.
That is the only lesson ages of necromantic study has ever taught.
OK so if Necromancy is so bad why read the one of its greatest works: Necromncy is the bastard child of two Arts. First is Nehekaran Theurgy, the power to meld divine lore with the winds of magic that the ancient Nehekarans called the Breath of the Gods (they were not wrong the winds do come from the Imaterium) and second is the Dark Elven art of wielding True Dhar that Nagash tore from the mind of a Druchi Sorceress. The interesting part about the latter is that even though we have no interest to weild Dhar, the fundamental theory is still elven, it deals with the same metaphoric understanding of magic that the Colleges use, we would not be trying to read an entirely new language, but rather have a translation guide, a Rosetta stone if you will. Now as it happens this Rosetta stone deals with the creation of weapons of mass destruction, rather than being a king's proclamation, but that is not what counts. What matters is the language it speaks, the magical; tradition of the first and arguably greatest human civilization. That is what we would be recovering.
What the Hell is this Theurgy Thing: Theurgy (used here to distinguish from Chaos Sorcery so as not to cause confusion) is the melding of arcane and divine magic in order to make magic safer for those who would use it, to soften the blow and preserve the souls of the dead against corruption and maleficence. It's about preserving not just Mathilde, but her brothers and sisters in Wizardry from death and a fate worse than death. This is not some unheard of or theoretical notion that only a dead civilization uses. The damsels and prophetesses of the lady make use of Theurgy too, as the Lady of the Lake helps them wield the Lores of Life Beasts and Heavens
What other benefits are there: The simplest one is that it will help us counter necromancy better. To put this into perspective a
priest of Sigmar use the knowlege of the Liber Mortis to unmake an undead army once. That is how potent the knwolege within is to those who would stand against the living dead.
With all that said:
[X] Resolve to read the Liber Mortis
