I have 3 questions.
The first one has probably been asked before, but will there eventually be legendary/folklore figures generated as well? Something in the vein of King Arthur or Robin Hood, where their existence is disputed and so on.
I'd guess in some worlds they could potentially be actual historical figures (though of course it'd be random as to which parts of the legend would be true, embellishments of the truth or merely made-up events) and in others they'd simply be subjects of legends and works of art.
This could be useful for modding as a replacement for deities and the like - so instead of worshipping deities, some races would revere and look up to the heroes of their legends.
Second question more related to modding: will there be a possibility of being able to mod in set historical figures that always appear in every generated world? As in, they'd always have the same name, race, and description - essentially they'd be constants in the same way as megabeasts and the like are.
Lastly, do you intend to have values affect societal structures in civilizations, as well as their behaviour? For instance, a civilization which values knowledge would be more neutral and send out more scholars and explorers into the world, and their people would give out more quests to get books in adventure mode; whereas a civ that values martial prowess would possibly have a warrior-king/queen with an artifact weapon and legendary combat skills, and a way to gain their respect and/or friendship would be to slay various beasts around the world and bring back parts of their bodies - skulls, hands, etc. - as proof.
