After barely rescuing Zetta from a witch-burning mob, Issak and the party make haste for the safety of Mergentheim, headquarters of the Teutonic Order of knights. They hope to secure safe passage out of hostile territory with the brotherhood, and to continue their search for Heinrich's missing brother. But when they arrive, they find the fortress curiously abandoned and the gate battered off its hinges. Before they can make sense of the situation, they come under attack from an unfamiliar foe and are forced to retreat inside, knowing full well they are falling further into a trap.
