This would be best made as a mod, to figure out how to do it, then integrated (as the Han were for A27). It's all good and useful to outline a campaign, but someone needs to code it, figure out cinematics, and do that type of stuff. If I were you, @CheckTester, I would refer to the Modding Guide and turn your idea into a mod, for insertion into A29 (it's probably too late to be added to A28).

It isn't a real problem, it just looks very strange.

Buenos días o tardes: -Disculpe me ,pero no le he entendido. -Si quiere más facciones asiáticas ,africanas e incluso americanas o puede que de Oceanía, le recomiendo ver el Mod :Endovélico (donde estamos desarrollando +65 facciones nuevas ), en el que estamos trabajando @Lopess y yo con ayuda de toda la comunidad. Si tiene sugerencias , críticas , dudas etc... sería de gran ayuda que participara posteando en el foro de dicho MOD. Muchas gracias.   Disculpen las molestias*

Not really, the dating of such structures is clearly falling in the Holocene. They are dating the underwater structures thanks to the dating of the environmental changes, notably a marine transgression in the case of Britanny. 1797401694_Fouquetetal_2025_IJNA.pdf It is not undermining the consideration we have for them. It is simply a description of their lifestyle. Using another label requires proving they are not hunter-gatherers.

I very much agree, but more work and interest should go into these discoveries. And we shouldn't narrow the field by calling the people that built them hunter-gatherers. It's interesting that many massive structures are found in deep waters, while others are buried in sand or sediment. This indicates that they were standing at least for 12 000 years, even before the last Ice age.
