Erfworld is a fictional location where the main story of the Erfworld webcomic takes place. The inhabitants, with few exceptions, are constantly at war with breaks only to rebuild and re-arm.
Erfworld is illuminated by a sun during the dayErf-b1-p007 and a moon and stars during the nightErf-b1-p035. It is unknown if the stellar system is geocentric or heliocentric, or even if Erfworld is in fact round.
Clouds and rain occur on Erfworld.
The people of Erfworld come from a variety of fantasy sources -- men, elves, gobwins, vampires, and many more species. Erfworld also includes fantastic monsters, such as dwagons and gwiffons that, despite cute names and appearances, are dangerous and violent.
A great many things are discrete in Erfworld that are continuous in ours. Unit's stats are always whole numbers. Terrain can be either a regular mountain or a high mountain, never anything in between.
Laws of Nature
Nature itself acts much as it does on earth.
People (known as Units) are governed by a complex set of rules not enforced on Earth. To learn the known (and speculative) rules that govern Erfworld, visit Erfworld Mechanics. Many of these rules are similar to what one might find in a Real World turn-based strategy game, but combat itself occurs in real-time.
Magic is real in Erfworld. Some people can cast spells which affect the world in ways denied by Science in the Real World. While most people that can cast spells are Casters, others can cast spells naturally. Magic can harm people, control them, create non-living creatures, and do many other things.
It is not known if Erfworld is a sphere, flat, or other form.
Seasons have not been mentioned.
The length of day is usually 24 hours, but time passes in an odd relative way, and can even occasionally seem to move backwards to a given observer.
Erfworld probably includes all terrain that Earth has.
