So, I was going through the apocrypha, catching up on omakes I've missed, and this one made me realize something. The Liber Mortis being Mathilde's great inheritance to her heirs—most likely Eike, yes—is… kinda weird.
Now, don't get me wrong. The thing has a lot of really nice knowledge, and gives people a pretty big apocalypse button, whether for causing or stopping it. And just having been in possession of the Liber Mortis is grounds for execution, which is a pretty hefty weight, to say nothing of it being Abelhelm's last charge. Yet for all of that, it is quite honestly the least important artifact in her story, and a poor legacy for some of those same reasons.
Where are the stories about Branalhune's inheritors, and it's legacy of service to Karak Eight Peaks and one of the eight commemorative swords? The Belt of the Unshackled Mountain, made in memory of when she tore down the black heart of Sylvania, and instrumental in her preventing another from forming? Or the Coin, a shard of stolen divinity that is both reward and responsible for her greatest feats and sacrifices in Ranald's service?
I don't know, maybe it's just me, but the big doom book that we read and then shoved in a box at the back of our metaphorical closet semi-permanently just doesn't strike me as the one thing Mathilde would consider her most important possession. A pretty big concern, yes, but not the most meaningful.
