Terranova was a continent in the western hemisphere. It was for all intents and purposes two large land masses connected by a narrow isthmus just north of the equator. It was bordered by the Arctic Ocean to the north, the Pacific Ocean to the west, the Antarctic Ocean to the south, by the Hesperian Gulf to the northeast, and by Atlantic Ocean to the southeast. The Hesperian Gulf separated northern Terranova from Atlantis. In between the northern and southern halves was the Bay of Mexico, which contained several volcanic islands. One British colony in Terranova was the Dominion of Ontario.
