I'd like to submit a theory to you guys (which I already posted in the Contemptor Dread BoLS post but probably too late for anyone to notice it):
First, the facts:
- at the moment FW is almost exclusively releasing eldar and heresy era space marine stuff
- the next IA book will feature Space Wolves and will be about the demise of an Eldar Craftworld
Does this remind anyone of a certain passage in Prospero Burns (minor spoiler ahead)? The main character discusses the Space Wolves with an imperial army officer who says he was there when they laid waste to a whole "craftworld" which is not specifically stated to be Eldar but clearly appears to be.
I hear people object: yes, but what about the Shadow Spectres "believed to be long lost" by Eldar Seers. Well maybe they got lost in that conflict but some survived, only to reappear later (a fluff excuse to allow them to be plaiyed in the 40th millenium despite the CW they were mainly based on having been destroyed).
Am I the only one to feel that this all fits rather nicely?
