Lantous is a female satyr, which is already rare, but she worships the goddess Elsam, who is the matron of traitors and the dawn. Her goal is to integrate into the nation of Emalon and steal the souls of the Freyaen population from right under their noses while also ingratiating the nation in her goddess' "goodwill".
She's a two-faced woman who sometimes truly regrets her actions but that shame is part of her faith, and she will embrace it even when it is hardest to do so.
