After her experience in the fog, and the mysterious stranger, Ylva had been feeling like she needed to actually look for something. The memory haunted her every moment, waking or not, and the decision had come in the spur of the moment. In the end, she had half-reasoned with herself, telling herself that she could look for something close by.
And, in the end, her paws had carried her to the place where she had first reunited with Brynhild.
She wasn’t quite sure what she was looking for- she just hoped that, even here, it’d be obvious enough. The blue glow, even in the fog, had been. Maybe, if Ylva was lucky, it would be something like that.
