Jack Linden here. Fun to see this topic pop up; thought I'd try my old login and reply (though weirdly it shows as a new account which is kinda sad).
Anyway, Jeogeot was just a bit of fun. Jeo = This (distant) and Geot = Thing. So it was a playful way to refer to a continent that was a long way south.. this distant thing.
I added Korean and Japanese words to have some localised characters on there (Home and Earth). I didn't decide to officially name them that, it was just to add some interest to the map.
