Dragon Slayer - The Collected Edition (2014)

Dragon Slayer follows three characters as they seek revenge. El Diel, an outsider to the bustling feudal metropolis of Bel Brixus, sets out to kill the king who has provoked the destruction of his kingdom at the hands of a dragon. In the wake of Bel Brixus' destruction, King Aldebrand seeks to kill the dragon alone and unaided, leaving his army in shambles and the population to nurse its wounds.
His city is smoldering, and with his kingdom still in ruins, he presses onward, aided by his right hand man Darius. El, meanwhile, follows close behind, waiting for his chance to bring justice to the king.
