Seed Code

The seed code is the definition of the world you will play in. It includes things that drive random world generation as well as baked in settings that will be used when playing. The code is made up of 60-bits of information, but is shared using a 12-character Base32 code. Some values affect world generation and others do not. Currently there are 44-bits of entropy in a seed code. That means that it is currently possible to generate 17,592,186,044,416 (roughly 17.5 trillion) worlds.
