Children of The Gods - S.A. Klopfenstein
This illustration will be a one page black and white image for the interior of a book called Children of the Gods.
This is a dragon fantasy series, and the first book centers on a Northern island, which is the source for dragon eggs in the world. The people on this island are Norse inspired, but less violent.
This scene is a magic action fight that takes place in a Viking temple. The shaman has a showdown with an imperial sorcerer-knight who wields a magic sword called a godblade.
