Kaulder

Kaulder is the titular protagonist of 2015 film The Last Witch Hunter.

Background
Prior to the main events of The Last Witch Hunter, the Witch Queen released the Black Death (also known as the Black Plague) onto England and soon half of the entire continent of Europe in the hopes of wiping out humanity and ruling Earth. Kaulder, and his team of witch hunters who are the early founders of the Axe and Cross Order, tracked the queen to her lair within a giant tree known as the Plague Tree, and they tried to kill her. She ambushes them, and she takes Kaulder to the tree's center. With his mighty iron sword known as Hexenbane (also called "Witch-Slayer") in hand, Kaulder stabs the queen with it; however, the Witch Queen retaliates by shoving her hand into his chest, and she curses him with eternal life. Unbeknownst to Kaulder at the time, the other witch hunters including the first Dolan found the Witch Queen's beating heart, and they secretly preserved it. Kaulder later went to work for the Axe and Cross, the same organization that was intent on maintaining a truce that was made between humans and witches. Kaulder was to be assisted by a priest that was known as a Dolan.
