Question about Twiceborn and death from old age

They don't. Except if they happen to be skilled in Nature and/or Death, or do some of the rituals that help against aging, or wear an item that helps against aging.

And what makes sure they will die off if the only way to die of old age is getting Disease? Knowing Dominions it is possible that they recuperate, luck out or something along those lines. I'm fine with death/nature mages living longer but I'd be displeased to see 150 years old regular men around. Because it makes no sense.

Endoperez said:That's a bit like saying that there should be a way to kill off a Vanheim Dwarf that's cast Invulnerability on himself, because he might survive being swarmed by a bunch of Principii for the 45 turns it would take for the forces of Pythium to retreat. Yes, it could happen, in theory, if nothing else happened (like the Dwarf routing, or becoming unconscious, or enemy mages casting something, or the Dwarf casting something), but it won't.

I think that example would be closer if you replaced the Dwarf with a Satyr infantryman.
