Mission boards will be filled by both myself as well as Co-GMs and player suggestion.

Transportation? That I didn't think about. Well, now is as good as any. I suppose there would be multiple ways of getting in and out. Man made underground passage ways with stairs from the early days of the settlement, maintained and updated over time. Gondola lifts as a more convenient option. There are functional streets but navigating the Waterways may be a faster way to reach your destination so boats are quite abundant. Maybe at least one or two train routes running through. Hmm...if you have any other suggestions feel free.
