This is meant to be Aegon I the Conqueror, who forged the Seven Kingdoms (okay, six) into one on the back of his dragon, Balerion the Black Dread.
The figure is from Fireforge's plastic Teutonic infantry set. I had to sculpt the scaled mail and turn the sword into the famous Valyrian steel blade Blackfyre, The head is from a Foundry Roman. I contemplated adding his crown, but decided against it. I will keep you posted on progress.
I may also decide to base him at the foot of a large black dragon that I already have. Decisions, decisions.
