The Osan Woods' Butcher fiasco had caused unrest throughout the kingdom of Edinburgh.
Many cultist organizations used the butcher as a metaphorical scapegoat to conduct their activities, putting the consequences in his name. Sara's family also suffered from the unrest that was created in the butcher's name. It moved to a completely different location without telling anyone.
Sara only kept contact with Katalina from her pre-shift life. And since the latter had her own life as a ranker, Sara stayed low-key in her new place with her parents.
Sara learned that there was a Rank-0 artifact available inside the capital city of Edin. It could pair up with a range of array disks and use them as inputs to render a visual image directly inside Sara's head.
The artifact had multiple functions. All of them were attuned to helping blind mortals "see" the world around them.
