Wierdly it might sell more if it's described as a Khorne fortress of skulls, than an as an Empire building, with skulls all over it. Either way it's too much directed at one of the warhammer races, though I guess it could pass for Nagash's new race, and other chaos races. And not generic, unless it's double sided with the other side of the pieces it has all lightning hammers.
I guess that means in the scenery pipeline we should be seeing
Realmgate Portals
Ophidian Archway
New Realm of Battle boards
Castle Grayskull or rather Castle Khorneskull
And I'm speculating that the other scenery piece spotted in Triumph and Treachery, which was a pillar with gargoyles is probably coming as well.
