Blond-haired, blue-eyed Acritasia converses with nearly everyone she meets, chatting merrily as she goes about her daily chores. She likes taking walks through the forest, enjoying the natural beauty of the trees and plants and creatures she encounters. She talks to the trees and animals, content to chatter with them even if they never seem to respond to her conversations.

Although she had conversed with Berthold in the past, learning that Berthold is in fact Arcturus Picae, a creepy magus, came as a bit of a surprise. She got over it, and he is now teaching her the secrets of magic. Acritasia attended her first Gathering of Twelve Years in 1251 AD, where she manifested a magpie Heartbeast. She enjoys flying and singing as a magpie. Following completion of her apprenticeship, she decided to join Insula Valaamis in distant Sarmatia.

Acritasia resides in Sanctum Acritasiae in Manerium Valaamis. She speaks Czech and Latin.
