In the lore there are some clues for this.
2. When the humans arrive, it is in a harsh winter. The lore says that if it wasn't for the elves, the humans would have died. This would seem to Indicate that they did not have any structures from Vas Demith. And it was not the entire population.
2. It does seem to indicate that they arrive with a chunk of their planet. The cataclismic events are call Collisions, so it would seem that a land mass has atru k the plant, albeit gently wnough for everything to survive. Flora and fauna from each of the planets are represented on Terminus. We have that straight from the deck a long while back.
3. There are no known Collisions that didn't bring life. This, I think, points to the reason Collisions happen and why the Celestials had to make a binding contract t with the planet's rulers, Eldar Dragons, not to destroy any of these incoming races. If only we could read the Dragon Accord...
But have you considered whether there were failed attempts? I still hold out that Sleepless was from Collision event that was perhaps abandoned. From the strange land masses in his Timeless realm. It seems to me that he would have destroyed the world so he was stopped in a Timeless prison, held so he couldn't do any more damage. The Tohrn have found a way to enter his realm to serve bim, maybe even Sleepless is the cause of the Murk.
