If you are a fan of the X-Men books of the very late 80s into the early 90s, right before Chris Claremont was forced out, then you know the guy left a lot of really convoluted and aberrant plot lines dangling. Then when Jim Lee, Nacieza and Harras took control, they pretty much completely ignored them.
This guy proposes a very detailed idea of how pretty much all the events were connected. If you have a chance or the time, its quite an amazing estimation.
In fact I wouldn't bet it was too far off from what Claremont had planned seeing as the Shadow King was going to have some dominance over the Inner Circle and use Gateway to access dreamtime was actually what he had planned...its all in there along with:
The Outbacks HQs computer having sentience
Why Shadow King is obsessed with Storm to begin with.
Storms mystical heritage
The N'Garais relation to just about everything
The Reavers relation to Gateway
He connects it all. Pretty good stuff, somebody give that guy a writing job.
