Amaurot is pretty cool but I don't really see a reason why we could live there. Bismarck is going to leave eventually and the place will be flooded again before long (even if it will likely never will due to time and game mechanic reasons).

I'm more surprised Mor Dhona doesn't have a residential district, or even Ildyshire. Both were built up over time and could have had one. Even Ala Mhigo could have gotten one.
