Katarina is the illegitimate daughter of Hugh Montbarron -- the former Grand Master of the Legion -- and a Lescanzi witch. Her mother's people are nomads and wanderers, distrusted by many people in Ehb... but they are skilled in both warfare and magic, and Katarina has been trained in their ways.

Katarina takes a thoroughly practical approach to conflict resolution: stay out of sword's reach, and settle your problems with firearms. With her rifle in hand, she can fell distant foes, and even the most resilient enemy can be brought down by her ensorcelled bullets and debilitating curses. When forced into close combat, Katarina uses sorcery and a pair of short-range side arms to repel attackers.
