I was perusing the web for some information on Crucible and found the following images by Clint Langley who produced much of the concept work for the game.
I must admit I love the original take on the forces he developed. Its really rather dark and even the usual good guys, the Elves look gritty and brutal.
I think I may have to have a go at sculpting up some bits and bobs as a homage! It will also allow me to have a bash at playing some games of Crucible too which is a real plus!
All the best!
