Sister Vasilisa is Father Kiril's young grand-daughter, and a Unknown priestess of a yet-unknown Old World deity. She lives with him in the Greenside Chapel.

Vasilisa usually wears a white tunic with red embroidery around her forearms, neck, and ends of her sleeves. Her long straw-blonde hair is free, and a red strip of cloth holds it away from her face; two symbols of the sun hang from it, on her temples, and a similar but smaller one is around her neck. Ladybugs seem to flock around her at all times, and she radiates warmth, love and kindness.  

A beautiful, carefree, if occasionally vaguely distracted soul, Vasilisa tends to the gardens, orchards and yards of the Greenside Farmstead, and is very fond of flowers, particularly poppies and starthistles. Her fair appearance is rivaled only by two things - her skill with weaving and tailoring, and her intellect; she enjoys speaking in riddles or employing wordplay whenever she can, which can make her a bit hard to understand when coupled with her aloofness. For her, words are not unlike fabrics or threads.

Vasilisa cares for Ladybug the Cow (whom she often gifts flower garlands), and frequents the grove and pond close to Greenside proper.
