Takes place just after they reach Skyhold, though I’m open to any part in the timeline.
She specializes in storm magic and conjuration, and has two empty hilts for spirit blades—think the Blade of Tidarian, but dagger-sized. She has a dual-wield style of fighting that she prefers over staff work, but she can use a staff. Myrna learned to fight with daggers before her magic revealed itself. She chose the Vallaslin for June because she is endlessly curious and loves to experiment with magic.
She attended the conclave with her cousins and lost them in the explosion. Her clan was mostly wiped out after a few terrible decisions. The remaining members of her clan have since been sent to join other clans.
She's grown very attached to her new family, however. Varric, Josephine, Blackwall, and Dorian are all tied for first.
She can and will pester people with questions, always willing to soak up whatever knowledge she can get her hands on. Solas, Vivienne, Dorian, and eventually Alexius, will get the brunt of it; no one is safe.
Disagrees with the title of Herald of Andraste but felt too pressured to reject it. She's not happy about it, but if it gives these people hope...
Sided with the Mages, spared Alexius, and has him researching for the Inquisition; she's constantly badgering him with endless questions to teach her whatever he can because she's too curious for her own good, much to everyone's displeasure. He tried to kill her and she's making nice with him to learn more about magic theory? They insist she at least take one guard with her for her safety.
