AFAIR initially it was "creation", but later someone (can't find his message) suggested that "genesis" would be more apropriate.
Agree that "creation" is a better notion for gathering shards to create a world. "Genesis" is more related to life creation, imho.
I think, that person thought: "OMG! Why the "Kniga Bitiya" in the Byble named "Genesis" (English version of thisa stuff) and WHY Eador named "Creation"? It is weirdo and not conservative!" And...
That`s was a story how was born Eador "Genesis".
