But even then, George might say one thing and mean something else. We don't know for sure, though. I think the only thing saving Legacy is that it's so far in the future from the current main storylines in the Expanded Universe. They have time to play with, and hoping George relents or dies without stipulating their continued survival in his will. lol
Remember, there are those who take everything George says literally as Canon, *cough*no bras in space*cough*. If he gets notified that they somehow died because of a loophole, and he didn't approve it, he is going to go thermonuclear on the offending author(s).
Pretty sure he'd be ok with natural causes with dying of time. I mean characters can't live forever, they gotta die sometime....unless of course your a DC character. Marvel was ok, they killed off a majority of their characters.
