Feels like wh40k
When things couldn't go worse, but still do... and than you top it down with a grenade to the face and stand half-dead with your balls out against a horde of tyranid.......
AND THAN SHIT HITS THE FAN.
So, next it is going to be Demons attacking the Nyds?
Well, that would kind of benefit the Eldar as a race by binding both a fraction of the Great Thirsty and the Nyds there.
Well, I guess "All Eldar Abandon Worldship".
So it happened exactly as that Spider Avatar/Demigod predicted: This Worldship is lost. All he could do was make certain the loss benefited the whole race somehow.
