OK, here is my opinion, and nothing more, but it is informed by MANY things said and unsaid on the History and Lore forum. That said, here is my "guess".
The new expansion,
The Shadow of Odyssey, will take us into the inter-dimensional spaces traveled by the
Shadowed Men (who are actually the
Shissar that escaped
Luclin before it exploded).
It has been revealed, by Vhalen in
his final gift to us, that "the Shissar knew their fate", well before Luclin blew and probably in time to move their temple again, from The Grey into The Void. Just one problem... having moved into The Void (aka Oblivion or Ethernere) they could not directly return to the material plane. Their only contact with other worlds has been through temporary portals (the swirl around the Shadowed Men when we see them) or more stable portals secured via the Towers. Still, they need mortal shells to allow them to stay for any length of time in our world.
Within the world we know, they have been searching for something they lost, something they believe will allow them to permanently avoid the doom foreseen in the Chelsith Stone... Ages End.
Others have been searching, too. Mayong for one, and his enemies, the League of Freethinkers!
How does Guk enter into all of this? I think that what the story we have read is relating is the original arrival of the Tower of Vul in the Feerrot!
