Shadowlord and chaos worshipper fluff

Does anyone know of any fluff about the chaos warbands in Mordheim and the shadowlord? Specifically I am asking as I have an idea to build a piece of terrain that would be the place where the chaos denizens of Mordheim worship, or give praise to their gods. Seeing as how the shadowlord is pulling a lot of strings behind the scenes I figure someone would be honouring him specifically somewhere somehow in Mordheim and I thought that would be a nice thing to build.

Any "facts" or stories anyone has would be welcome, as would crazy ramblings and brain gibberings on ideas for how chaos followers would worship in Mordheim. And specially what shenanigans the shadowlord would encourage his followers to get upto.

Thanks!

As far as I can recall, the Shadowlord live in The Pit (the place where the comet hit the town) and his worshippers (the Cult of the Possessed) gathers wyrdstone and throws it down to him. Some go further down to receive some gifts (Gifts of the Shadow Lord optional rules) and I suppose the Magisters are doing some scary rituals with their captured foes and all.
Perhaps you can find some info in the fluff part of the Cult of the Possessed warband rules.
