When was it–the first time Ansgar began having vivid dreams? At first, he treated those dreams as mere dreams. Despite how real the dreams felt, he dismissed them until he couldn't anymore.
Ansgar was smart, perhaps one of the smartest people Reichwein had ever seen. He was quick to grasp the meaning of those dreams. Placing the pieces of puzzles together was an easy task for him. In fact, he found joy in mastering the challenge.
He wrote down the sequences and each detail of his dreams and worked toward building the correct timeline. This allowed him to notice that more than one timeline existed.
The first one or what he called the original timeline was before Runa and Yohana swapped places. It was at this timeline that Runa sought the witch.
