Interest Check Thingy (NEWER POLL!)

I think a small human establishment could be interesting, and maybe there's a Clan that makes its home in the middle of/near a market the humans have (perhaps they live off of swiping fish, and they're the most friendly towards Twolegs and this Clan is difficult to invade without alarming the Twolegs?!).

As for the Clan's ancestors, they might have gotten on the ship as the ship's cats (most of them only being kits and a few adult cats as the mousers) and the ship might've gotten stranded on an island and the humans tried to make the best of it. The cat population increased when it turned out there were some natives on the island as well.

Adding on to the previous idea, the current Clans could be divided into cats with their ancestors being natives and the stowaway cats, OR the genes are all mixed up and some cats can boast about having native/stowaway ancestry like how some of the gorge SkyClan cats could claim they had ancestors from the original SkyClan unlike those with purely kittypet ancestors.
