Perousing thru the "players/GM sections" of the book - those that aren't explicitly banned info for players - I've read the statement that 1) there exists an exsurgent virus & that 2) its "very likely" of alien design. Isn't giving out this Big Secret too much? Or is the whole focus of the default campaign to be "the few in the know"?
Also (ignoring the RAW), do you think it's best to "misinform/keep hidden"* sentinels about the exsurgent virus & it's ramifications, or just let it ALL in the open, because they already have enough stacked against 'em in the first place (i.e., knowing about this won't make a difference)?
