Haven´t read anything about those two yet. There will be children, right? Or are immigrants your only way of getting people? I mean love stories and childrens would definately add to the drama.
Pretty sure children will be there. No idea about marriage; 'tho it'd make sense to have it, i personally could live without it. Too many ramifications in the relationship tree might mess up things quite a bit. We really don't want this to turn into the Sims, do we?
There will definitely be children at least as urchins. Whether urchins are created when they lose both parents or whether they spontaneously generate from piles of bronze shavings and discarded crimble isn't yet known.
