One of the projects I've completed recently is a war litter for my Skaven Warlord:
The litter is carried by clanrats from the Island of Blood set. They are holding a rack of spears, upon which the base of the platform is mounted. The main platform is constructed from basswood strips and covered with metal plates and shields. The back of the litter is part of an Empire cannon, topped with the Island of Blood warlord banners.
It was assembled in true Skaven fashion, because the entire construction came from spare parts scavenged from by parts bin.
The floor of the war litter is cut out so the model can stand in the recess. This allows me to use it for either of my two warlord models. (Of course, Lords Skreekits and Skabsis will now have to argue over which one of them gets to be carried into battle like a king!)
