I won't speak for everyone here, but for me it's not that I'm not sure it is linked, but it's that there is no evidence to link the two together.Guys why are you sooo sure this story is not linked to Formidine Rift / Heart & Soul etc.?
Yes, there could be something interesting to be found by following the Formidine Rift mystery... but nobody has found anything connecting the two yet.
If you actually find evidence of this, by all means, post away. But until them, it's incredibly foolhardy and would lead to a lot of wasted effort to blindly assume the two are connected.
Certainly both warrant looking into, but lets save calling them connected until something actually does that.
Cue people saying "But <Person A> said X and Y" at which point I cast disparaging looks.
