INK ( Robin/Al-an -Mermaid AU)

Notes:

Takes place on a post flooded earth, land is scarce and often swallowed by the rising tides daily, humans have taken to the water and over thousands of years evovled into mermaids, much of the knowledge of human civilization is lost but not fully forgotten.

There is a semblence of society but due to the strained environments much of culture was regressed into a more mordern tribal structure societies scattered in little to big settlements with their own unique territory..

Many tools and necessities have evolved with them but things like phones tvs and other things were lost in the great rising.

Al-an is a creature (glosses over orgins )
That is an amalgamation of leviathans, namely the crab squid and shadow leviathen.
