Looking for an undersea city or palace

[Kangaroorex]

Hi everyone, 

 

Does anyone know of a module or resource that has a pre made undersea city or palace?  One of my group paying saltmarsh took up the sea elf Prince when his character drowned  and then promised the support of his city.  Now the party wants to visit the city and negotiate for those resources.  I want them to have a good time and have at least the trappings of a city around them but I don't want to build and populate an entire city in a week or 2 for a 1 week adventure that could, potentially become a rerunning resource but might not.

 

Does anyone know of a module or supplement for an Atlantis or similar city below the waves?

Antimatter Games has undersea games and stuff, not sure if it's useful to you.

Citadel of Gold and Blood Reef, Deep Wars. etc

Check out in particular D&D Stormwrack (3rd Ed, environment series--kind of awesome).  Waterdeep (as a keyword in searches).  Also check out dmsguild--the site lists books for sale so I won't share the link itself. 

 

If you need terrain, you can of course hit up your local pet store and raid the aquarium section!
