Argentea was originally created by Paizo. She appears on Reign of Winter adventure path. Her backstory and character design have been adapted by the artist Leila Ascariz and her gaming group.
I modeled out, printed, and primed this character as a submission for one of Leila's contests. It was left unpainted for another artist to do.
Leila's Pathfinder adventure with this character can be found here: https://leilaascariz.deviantart.com/gallery/64725346/Reign-of-Winter-Literature
