"It wasn't your choice? What happened?" Sierra asked. She didn't exactly sound sympathetic (the fact that she was still smiling probably killed any chance the question would come across as a genuine display of concern), but they were something like family in an obscure way and she was at least interested in hearing how he'd ended up like this.

"Falena? The Dawn Rune?" Sierra's eyes shifted back to Frey, reappraising him. She hadn't taken him for a person from her... world. She wasn't really the sort to worry, but she could see why the Sword would say such a thing. Moon, Night, Eightfold, and a fragment of Sun, all here? She wasn't an expert on True Runes other than her own, but even she knew this represented a concentration of power to rival even Harmonia's collection of True Runes at its height.

"It's probably your Rune, then," she said in response to his disagreement. A runic vampire wasn't harmed by sunlight, but it wasn't surprising that its concentrated essence would be discomfiting for a creature of the Night.
