The Sanzhani Tsarina is a moth-like fairy who rules the Sanzhani burrow and carries Coen's secret messages to Lunka. Her quests start with Good Home in the Svartrau Outskirts.
The Tsarina is a winged fairy who keeps the human girl Heile in her burrow and considers her rescued. She is touchy about her guests but happy to do business.
Head north from the Sandy Gorge Shrine any time after the prologue and follow the mushroom rings to the burrow. Good Home is the first quest she's part of.
Through the Tsarina, Coen trades letters with Lunka in Letters to Lunka. The other Sanzhani give Coen more tasks across the valley.
Lunka
Lunka is Coen's youngest sister and the one he is closest to. Brencis takes her and the rest of the family to Greifberg Castle, and she writes to Coen from inside.
Tonis
Tonis is Heile's brother, a coal burner living alone in the woods. In Good Home you track him down so he can decide whether his sister stays with the Sanzhani.
