A mainland or land-block is one of sundry big deals of land on Earth. There is no true meaning to the word "mainland" as it is hard to say where one ends and one begins, but folk widely see the world as split between up to seven deals known as "mainlands". These are (from biggest to smallest): Asey, Africa, North America, South America, Antarctica, Europe, and Haffland. Smaller deals of land may knit some of these together; as a byspel, some works take Eurasey or America as together being one great mainland.
Earthlore-wise, the mainlands fit to deals of the Earth's outer layer that are found on the landrafts, but also inhold smaller stitches such as Madagascar that are not often seen as mainlands. Some earthlorely mainlands are widely shrouded by water, such as Zealandia. Mainlandly stitches are only known to be on Earth.
Offshore ilands are often batched with a neighbouring mainland to split up all the world's lands into steads. Under this draft, most of the ilands in the Great Eastern Sea are batched together with the mainland of Australia to make a new deal named Oceania.
