Revenge is in the past. The Circle Order and the Council of Four accomplished what had been considered impossible for sixty years--they restored the Chaos Clan. The Greymores are no longer in disgrace. We are once again granted the title of a Great House, yet it brings me no joy, because inertia of thought is a terrible thing. Chaos mages are still seen as dangerous criminals, and not even an edict from the Emperor could change that. Besides, now that the Greymores have a home of their own, it's much easier to hunt us.
So be it--let them hunt. Who would object when resources practically floated into our hands? We certainly aren't about to refuse such a gift. As for everything else, we will handle that too. The Greymores know no other way.
