As seen in the Languages page, Swagxolotl made the language of... "the epic swaggy guys" he insisted a set of 1k of each species be put on an island to coexist and they all speak "Swagxolotlian", he named the country "Swagland" and made them all "Swaggy", the people there immediately ended up fighting because mermaids inherently have vastly different needs to the land based humans, neanderthals, and denisovans, who have different needs than fairies, and after heated debates the state collapsed into war and Lucy had to nuke it because the language started becoming just swears.
Swagland was quickly cancelled, each of the people groups were distributed to new homelands, and the island Swagland was situated on was left uninhabited until 495 when a local nation on the nearby mainland claimed it and set up a province there, keeping sure to record everything and ensure history is preserved, because a God literally did this, it has significance.
Swagxolotl remains upset that it failed, later on Swag Bay would arise on it's own and he was honored they honored his gifts of swag.
