(The Throne of Souls)
Liche Priest Solium Animus riding Grenadier's old palanquin, with Heartbreaker (I think) guards. This one's cool because you can sight through the skull's eyes to see which hapless enemy units might be able to see those souls coming at them. A True Line of Sight visual aid! Still shorter than the official GW casket, so I'm not gaining any advantage from the alternative model.
