Like all place names, it is by consensus, yet starts from the idea of one. The Emergery is the name used for this continent, and all of it that has been mapped, by the wise folk, the wizards, scientists and such. The origin was one of either Samuel or Sebastian Poultice, who created a bestiary of the same name.
The name was meant to reflect the sheer number of creatures who are either evolving or coming out from the shadows, which was their inspiration to begin with.
The Royals name their lands (often the whole continent) after themselves, while common-folk have no use for naming the continent, for few understand that it is a continent and fewer have ever spoken to someone from abroad, or even read a book.
The Emergery has also become a science, as the philosophers try to understand why all the changes are occurring.
The animals, birds, fishes, trees, monsters, microbes and whatever else can talk have their own name for their world, the old name, which translates to something like The Edge Of Everything Turned Inside Out.
The Poultice twins did not complete their bestiary in their lifetime, but some of their grandchildren did, with the help of many brave souls (and lucky accidents) along the way. Saying that lives were lost would be an understatement, but the rewards offered by the Royals were very tempting. Many tales of discovery were recorded in a companion piece.
