Thanks Druchii Monkey, a great read - interesting stuff. I like how Gav engages with the fans like that.
This theory of DE birth rates is actually one of the few bits I disagreed with. Simply have more sex outside marriage wouldn't necessarily lead to more children as there would be no gain to the individual female in keeping all these bastard offspring or letting them be born - unless it was to sell them as slaves. As for the comment on raiding the rest of the world to widen their genestock surely that can only lead to half-elf children.I particularly like this bit as it describes some interesting observations by Gav Thorpe on DE and HE.
"I really wouldn’t like to put a number on the population levels – from a writer’s point of view it has always been that there are enough for whatever purposes the story needs. It stands to reason that the Druchii numbers had to expand somehow, they started off as a single kingdom and are now a nation unto themselves. Having left behind a lot of the traditions and taboos of Elven society I would assume that there’s more breeding going on in Naggaroth than Ulthuan. Also, the Druchii are a it more dynamic in culture, outgoing (if only to go out on raids!) whereas the Asur have become insular, drawing on a dwindling genestock and bound up by generations of familial ties and traditions."
Gav said earlier in the Q&A that Dark Elf Society 'works' for the sake/context of the setting, but if you try and analyse the specific mechanics of it too much then it just falls apart. I think population numbers is a good example of that.
