GW's Eldars' Fire Prism (plastic, by Jes Goodwin and Tom Walton)

+ GW's Blood Bowl's dark elves star player Tuern Redvenom (metal, by Alan and Michael Perry), Citadel Miniature Red Catalogue p. 320.
+ a scratchbuilt flag using an aluminium sheet from the top of a bottle of wine (a material with a great flexibility)
+ a Secret Weapon skull base, in which a rectangle has been cut so that the horse can be removed from the plinth and be used to play with).
