On 9 August991, the TracersAbby and Zara arrived in the town of Maldon in their search for Marek. By the next day, the sisters had discovered Marek's absence, but still decided to stay to help avert the complete destruction of the town by an impending Viking attack. Struggling to do so, they kept jumping back in time and altering events, with each change causing new problems. Eventually, time began to unreel, so the sisters knew they had one chance to affect events before they used their powers to fix it. They sought the help of a future historian, Chi, and the timeline was restored to its original state.
