I really included everything that Alien The RPG, The Cold Forge and new material since don't contradict. It presupposes nothing, this is the way it is, nothing myself or anyone else can do about it. No, a reference does not therefore make that story canon, that's fairly obvious. It makes for example, a location with the same name canon, but nothing else. Everyone's got their own canon to a degree, but it's ultimately meaningless in the face of official canon, the basis for conversation that goes somewhere. If you're correct, and you're not, that no official canon exists then no common ground exists for conversation as everyone gets to choose what matters. Do you think that's the way it works internally- it's not- so it's not the way good faith conversation is externally.
