History
Krall became a supporter of the Dark Wizard Gellert Grindelwald, and at some point joined his Alliance, the goal of which was to expose the magical world to non-wizards and then take over the world using magic. He became of of Grindelwald's inner circle, and accompanied him to Paris to recruit Credence Barebone. While there, Krall expressed doubt that Credence would be able to help them, and Grindelwald asked him if he would be on their side when they achieved victory. Krall quickly replied that he would, but Grindelwald was skeptical.
During the battle at the Lestrange family mausoleum, Grindelwald created a blue fire and asked his supporters to jump through it to prove their loyalty. Vinda Rosier got through unharmed, however Krall was not so lucky and burned to death, therefore showing Grindelwald was right not to trust him.
