Sorry Storm. The Imperium has never had any planets within the Ghoul Stars. The Pale Wasting was an event when some nameless horror from the Ghoul Stars came out to mess up eveyone's day. So they can't have a world in the Ghoul Stars. Besides there would be no point to placing a Space Marine Chapter there. The Ghoul Stars are way, way out on the fringes of the galaxy in the galactic east. The Imperium wouldn't place a Space Marine Chapter so far away from their territory without good cause. They placed the Death Spectres there after they realized what a massive threat the Ghoul Stars and their inhabitants posed, but it is unlikely that they would put one nearby before the Pale Wasting. Regardless holding Imperial Territory within the Ghoul Stars themselves is out of the question regardless of the time it happens.
