Yes, this one's come up a few times on the Forum before - I've mentioned it more than once, I know! - but there isn't a "Resources" topic for elements like this. Might be worth adding one though?

Well if we're talking gazebos - and this famous one particularly - you might care to take a look at this Pay What You Want paper mini on Drive Thru RPG:

I appreciate the problems with getting the symbol to work right, Sue. And this one will look good as the tops of forest kelp and other denser seaweeds, aside from its intended eelgrass, so it's win-win, I think!

Mysterious Island keeps coming round on British TV from time to time still. Perhaps most famous still for containing some of Ray Harryhausen's excellent stop-motion animations.

Thanks very much Remy!

It's great to know the Atlas has grown so much, especially with the recent boost due to the winter contest. Amazing to think when that competition began we were still a couple of maps short of 500!

Julian makes an interesting point here about other undersea settings than fantasy. There are probably more options to set people thinking of underwater adventures in fiction for the alternative-Victorian to modern periods than the pseudo-medieval fantasy one overall. Quite a number of the Bond movies from the 1960s and 1970s involved some undersea elements, for instance. Personally, it was the 1965 Thunderball film that started me thinking about underwater games more generally, partly because that was coupled with a lot of cheap plastic toys around then that were (often rather loosely, for which read "copyright-avoiding") based on that movie. That influence has never entirely gone away. There was also the Gerry Anderson children's TV series Stingray around the same period (1964-65), which was set in a then-near-future-looking 2060s.

I'm not sure this moves things forward in this project however, since there are already CC3+ assets to cover much of these settings (admittedly, while needing to repurpose or adapt for some things), so the sea-bed setting is probably the key thing for this project, and by the looks of things so far, that seems to be getting some excellent coverage already!
