The Bay States

Primarily Valaya, Cetyt, Orendiji and Kiyik. Maybe Efi too. The bay gets a huge amount of marine biodiversity. Semi-civilised to the degree of colonial India or Brazil. Some peoples there are aquanomadic, so lots of opportunity for culture expansion. Starfish clothing

Good for bioluminescent waves.

The main theme connecting Kiyik's city-states is an antitheistic view. They do believe in God, but they despise Him and think that he's an asshole. Deliberately trying to piss him off. For them, their God is in the form of that giant sea dragon and they started hating him after they saw Him start the screaming seas.

The West also has a vegetable which is essentially an edible version of cotton. Thin, elongated leaves. Unique taste and a faintly orange colour. They also have rice.

Pack Octopus
Smallish hand-sized octopuses which are used and reared intensively throughout that large Western bay area. Although not fully domesticated, it's pretty close and they are kept in tanks like lobsters, and are rather tame. Smart enough to know humans won't hurt them. They are mostly reared for their ink which, by a curious twist of evolution, just so happens to be edible. It can be mixed with other ingredients to form black hard blocks, fermented or used as a sauce, as well as for whatever purposes I can't come up with on my own. The octopus itself is effectively milked by wrapping itself around a hand and releasing ink after a gentle squeeze. Frightened?? I'm not sure yet of the social and political connotations. A dark beige/khaki colour, resembling flapjack octopuses.
