Image: Rebel Wolves / Bandai NamcoNo screenshot of Zdislav yet. This one shows Laslea (Rebel Wolves / Bandai Namco).
Zdislav is the wise old alderman of Laslea, Coen's home village. He is a lore figure from The Secret History of Vale Sangora whose diary warns the young about the valley's dangers.
Few Sangorans live long enough to warn their grandchildren of the valley's dangers. Zdislav is one of the rare exceptions.
The sources place him in the Secret History series rather than in a quest. Read those parts for his diary and his view of life in Laslea.

Alin is Coen's younger brother, who drowned as a child after falling through cracked ice. You never play alongside him, but his death shapes Coen, his mother Esme and the quest Home Sweet Home.

Anca is a former nun and herbalist living near Laslea. She taught Coen to read Latin, and after Laslea falls she teaches him blood magic, starting with the hex Compel Soul.

Coen is the main character you play. A young farmer from Laslea, he becomes a Dawnwalker, human by day and vampire by night, and has 30 days to save his captive family from Brencis.

Esme is Coen's mother. Grief and illness have left her barely able to eat or leave her bed, and getting her through the next Blood Mass is what drives the prologue.
