Just as the sibling mentioned, Darkholme was in chaos lately. The gates were closed, and the guards refused to let anyone in and out of the large city. However, Eve found a way to get in by reading Marmon's memory. Since they were children, reading their memories did not require much.

She stood on top of a large tree not too far away from Darkholme, her gaze dark and solemn.
