Fallen Kingdom-related events? 

Well-documented cases of madness amongst ship crews (Iolanda, Ruby Delver, Osmosis XXIV).

Also, the voices. Not the incoherent, distorted babbling and moaning commonly associated with Ghastforms. Very faint, muffled but perfectly understandable instructions. Regarding nonexistent (undiscovered) places and structures. Some were mentioned more than once*.

And the visitors. The Knight. The Messenger. The Lady. And numerous others, unidentified or never described.

For me, it looks like the Fallen Ones want to convey some kind of message. And I don't think that we are its recipient.

There were some GDS that originated from Hexspace. Damn, even the very first one originated from Hexspace. 

But I've seen more than that. I've seen cairns on lifeless moons, perfectly in the middle of craters.

I've dreamt of doors to nothingness - portals leading to places devoid of everything except the howling wind.

At least two tips of the Triangle converge in Hexspace. Also, there are other visitors. I'm sure of it. Other entities. No, no the tttttnrh, they seem to avoid Hexspace at all costs. Maybe rogue droneships from the distant past. Maybe non-human intelligence. Maybe even some forgotten Homunculi.
