As stated prior I wanted to bring the war into ArtWar and portray two fantasy armies clashing in battle, supported by a masters of the elements that could turn the tide of battle. For my narrative to hold some logic the extent of these powers must be constrained, for if these elemental champions could wipe out an army with a flick of their wrist, there would only be duels between elementalists and no place in war for the common folk. My answer to this I settled on was a champion that could animate elementals of their faction. Not only did this reinforce my initial idea of massed troops, but could also help distinguish the champion in a crowd.
The question of attacking or defending could be leaned in to heavily from either side of a siege or city fight. I liked the potential of expanding on the champions culture through their peoples architecture, so decided on depicting the champion defending in a city or town. Whilst there was temptation to subvert expectation, I decided to take the safer rout and depict those of the earth faction defending and suggest they were being attacked by a fire faction. To further make the champion stand out I decided to make them a human fighting orcs, so there was an instantly perceived good guy vs bad guys and fantasy dynamics.
The more creative characters designs were the earth elementals, and as I had the initial idea form them from large geodes and incorporate geometric metal crystals in to the joints, I decided to concept these first.

I felt the design came together well with a strong organic shape with good variation between big and small body sections. The geodes gave a sense of more magical yet fragile insides, and gave a good variance in colour and texture. I wanted to have a face without eyes to suggest that these are not independent beings, but are bound to and depend on the one who summoned them.
