I was looking at Celestial Hurricanum as for late, and it struck me that most of the rules it has would perfectly fit Disposssed "Anvil of Doom" equivalent. Storm of Shemtek works well as "Rune of Shattering", +1 to hit is some generic "buff from ancients" etc.
In general its also good for Dispossed to proxy old (great) Anvil and just use "ally" and rules from celestial hurricanum.
