I dunno, I encountered the Lich quest that spawns from the Plague event for the first time yesterday and it seemed, thematically, like a pretty good fit. The event itself presents three difficult choices, each with a cost, and the one I took lead to an unexpected and unfortunate consequence. The fact that I was playing as Ceresa added to the irony too.
True, the undead are a stock fantasy race, but I think they're a good fit with what I see as two central themes of Elemental lore: the 'broken world' and, in the case of this event at least, unintended consequences. Not to mention that, with the Wraiths and the Butchermen, there have been various kinds of undead knocking around for a while even before we had skeleton hordes.
Also, clearly I'm going to need to read up on the Cinderbones, I haven't read anything about them yet and only encountered them once. I also like Banshees simply for the tactical challenge they present - playing as Resoln I have been able to handle them because Wraith Touch affects them even if I have no mana or spellcasters, but in my last game as Yithril they were formidable.
