World Anvil is an online service for documenting imaginary worlds.
Imagine a wiki but with custom content types designed for worldbuilding - such as maps, timelines, character sheets, cities, locations, creatures etc.
Who created World Anvil?
The project was started in June 2017 bu husband and wife team Dimitris and Janet.
This is a holding page where I'll publish my review of World Anvil. Until then, head over to their website, sign up and see for yourself.
