"Why?" Ambro thinks for a moment. "Have you ever heard of the apostles of Hell?"
Not waiting for an answer, Ambro continues, "They were the seven children of a powerful demon of the Western Nothing. They had the job of tempting humans to sin, for each of them represented one of the seven sins. They did their job well, until he came; he was a spheremorph, one of those stock paladin types." Ambro looks at his spheremount, strapped to his arm.
"Many of the apostles were killed outright when they confronted the spheremorph, two, Greed and Lust, fled with mortal wounds. Upon the road they discovered a traveler, who was an ancestor of mine. My ancestor was tempted with greed and lust for the power of spheremorphs and snuck into the city...then stole the spheremount and formspheres of the spheremorph."
Ambro gestures at his partially scaled skin and half black half red hair.
"But the demonic influence has never left my bloodline, and I still feel hatred at those like that paladin spheremorph. I only wait for the proper moment."
