So this is a bit of a random question, but can a spirit that takes on a body reproduce? If so, how does that work genetically with DNA and all. Is Ancient Elvhen magic powerful enough to just come up with very specific and unique DNA? Is this spoilery? Or did you cover this already and I missed it? I keep feeling that maybe part of the reason canon!Solas said "I can't" is because he could never have children with Lavellan?? Makes me wonder about Cole and the bard, as well. My brain hurts...
I haven’t talked about this, actually!
Dreaming-born can totally make babies. But one of the big physical differences between Lavellan and the ancient elves is that Lavellan has generations upon generations of breeding behind her, whereas most of the ancient elves have far, far less. Dreaming-born elves are basically ‘first generation’ elves with constructed bodies that operate like normal bodies, but are all built pretty much the same way. Between low birth rates and immortality, even the Waking-born elves don’t have that many ancestors behind them. Compare that to Lavellan, who comes from a time when elves live a hundred years, if they’re extremely lucky, and every generation had to reproduce at a rate that would boggle the Arlathan elves if they didn’t want the population to die out.
What that means is that Lavellan is full of genetic quirks and things that simply haven’t had time to develop in the ancient elven population, as well as evolutionary traits that developed for survival thanks to natural selection and whatnot. I don’t know if she’d have an easy time procreating with Solas. There’s a pretty big gulf between a first generation elf with a body made fresh off the factory line, and a way-way-way-more generation elf who hasn’t had a first-generation elf in her family tree since shortly after the Veil went up.
