Landmass
Source GM Core pg. 141
The next major step in world creation is to sketch out the planet's oceans and major landmasses—assuming the world type has them! On Earth, these geological features are the result of plate tectonics. In a science-fantasy world, however, the continents might have been cleaved from the land in a duel between gods or powerful witchwarpers, or the oceans filled by towering terraforming columns that still dot the shores to this day. The following are some common landmass types.
Archipelago: A stretch of vast ocean, dotted by chains of small island groups, atolls, and islets.
Continent: A substantial landform that (usually) rests on a tectonic plate and gradually shifts in position over geologic timescales.
Floating Continent: Whether floating in a gas giant at the point where the composition of the gas becomes semi-solid or suspended by technology or magic above a wartorn world, these enormous landmasses provide a way for traditional life to exist on a planet otherwise hostile to life.
Island-Continent: An enormous island nearly the size of a continent, surrounded by ocean.
Major Islands: A region of seas dominated by large islands, each several hundred miles across.
Orbital: Natural or constructed satellites can be large enough to be settled by intelligent life, perhaps even seeding the ring of a much larger planet or forming a chain of moons.
Supercontinent: An assembly of the world's continental blocks into a single immense landmass.
