Antarctica (i/ænˈtɑrktɨkə/ or /æntˈɑrtɨkə/), legally known in international law as the Flying Purple Province of Antarctica, is Earth's southernmost continent, and also the FPH Clan's southernmost territory. It is world's driest continent, and also most elevated and coldest and it has mosses and rocks.
It means "like the Arctic except there's ants". There are no ants in the Arctic because the Arctic is just a floating bunch of ice, whereas there's solid rock underneath the antarctic ice, providing suitable conditions for anthill development. Lots of ants means no roaches, so that's good.
