Kasper von Liebenstein

Kaspar von Liebenstein was the main author of the Witch Hunter's Handbook, a collection of doctrinal and scholastic texts issued to all members of the Order. His current whereabouts are unknown, but considering his age and accumulated injuries, physical as well as mental, he is presumed fallen in the line of duty. To commemorate his memory, the exceptional quality Liebenstein Rapiers have been crafted by the very best of Altdorf's blacksmiths.
