Moenbryda is a Seawolf Roegadyn woman with pale skin and silver hair. She has the Circle of Knowing tattoo on her neck, as well as a large red tattoo on her left thigh resembling an eye. She wears a blue trenchcoat with a white hood and a short blue skirt and high boots. She carries a Dual Haken axe.
Moenbryda is called in once the Scions are unable to find a way to pursue Lady Iceheart after she escaped Snowcloak and seemingly cut off or destroyed her destination Aetheryte. Using a crystal called white auracite, Moenbryda attempts to perform a trace of Iceheart's teleportation to allow the Adventurer to pursue her. With this, the Akh Afah Amphitheatre can be reached where the heretics' primal Shiva can be confronted.
She sacrificed her life so that the Warrior of Light could make a blade of aether to destroy Nabriales.
