Canon vs. Fanon Content

I am not sure what to write here.

Canon is obviously the official texts that the game are based upon and the texts backstory and world history, that comes with the game. Ref: https://en.wikipedia.org/wiki/Canon_(fiction)  

Fanon: https://en.wikipedia.org/wiki/Canon_(fiction)#Fanon  

Fan fiction: https://en.wikipedia.org/wiki/Fan_fiction 

Does the Homeworld fan writers have another take on this?
