Status: GLOBAL NUISANCE
It is not clear when the Deep Ones rose from the sea, but nowadays they occupy huge swathes of land, mostly in coastal regions of the equatorial zone, and are a serious danger to neighboring lands, as they're huge in numbers and definitely hostile. They seem to worship some sort of 'Old Gods' or whatever - these Gods aren't the same as Star Gods, but aren't their enemies either, and are said to live in the sea. They're also apparently at least equally nasty.
