This is a piece of background art for my "Battle for Wesnoth" campaign, "The Elf, the Dwarf and the Mage". The dwarf of the title is Alatos, who is an engineering genius; he is the Wesnothian inventor of the steam engine, which, given the general instability of the place, is initially used as a fighting machine rather than for transport. It does some unpredictable things on the battlefield, which I had a great deal of fun coding. :-)
I don't know what Alatos is building in this picture, but I'm sure it's extremely steampunk.
