Blue Arya is Damon's former protagè and the spymaster and the youngest of Damon's most trusted allies.
Damon was impressed by the girl bravery, since she attacked him even if she standed no chances and decided to adopt her.
However, when she was 10, her uncle house was attacked by many demons and she attacked them, trying to save her uncle, however she was saved by Damon, who came nearby, hearing the screaming.
In other words, she regained her soul—or, if you prefer, stopped being such a know-it-all teenage shit, with the black-and-white ethics to match.
The clerks, too, when I went, were almost exclusively of Sri Lankan descent.
She is mixed of Irish, Cherokee, and Russian heritage.
