Inquisitor Heinrich von Hexenhammer is mostly an average dwarf... mostly. He is taller than most, but very lanky - as if he's always missed his last few meals. While many non-dwarves would conclude his attitude is what they see as "typical", dwarves would hardly agree. He is strict to the extreme, especially concerning the topics of debt, vengeance, and witchcraft.
The first two make sense enough, if one were to recognize the holy symbol to an obscure dwarven deity scarred on his forehead. Dranngvit is seldom worshiped even among dwarves, though many pay her lip service concerning her portfolio of debt, pursuit, and vengeance. The few actual worshipers of her are considered less then mentally stable when it comes to enforcing their beliefs.
Heinrich's issues with witchcraft stem from a vision he received from Dranngvit during his seminary, which urged him to travel to Ustalav and purge the lands of those using foul magics. Though the true purpose of that mission has yet to unfold, Heinrich is affirmed in his belief that he's on a mission from (his) god and can do no wrong.
In the mean time, Heinrich has been working as a tax collector for various Ustalavan lords to better finance his witch hunting. As it is well known that witches seldom pay their taxes, the two work well together.
Ah yes, the Professor. It's been a few years since I last consulted him concerning witchcraft in the area, and even more since our first encounter when that tax evading witch attacked him. He had proven a stalwart ally in my quest, and it would only be right to pay my respects. Besides, he does still technically owe me for that other time involving those gnomish circus clowns... looks like he's finally going to pay that debt, and I intend to collect in full.
