Greetings, Brother Librarians. I write my inquiry from the planet Cartonus, where elements of my chapter are currently engaged with a most tiresome group of Eldar witches. My question is this: why were these troublemakers not given the Emperor's justice along with other xeno scum when the chance was at hand immediately following the destruction of the traitor Horus?
You have my gratitude for a speedy reply.
The Emperor protects.
The Eldar Craftworlds are incredibly stealthy, the Imperials just can't find them. Once they did and actually attacked a craftworld, and lost an entire sector fleet in the process. Since then, the Imperium hasn't attacked any craftworlds.
Also, the Eldar are allies as often as they are enemies.
