The Fates

Before arriving in Barovia, Dusk had her fortune read by a strange old woman named "Rose", who she knows suspects of being a disguised hag. Each card was linked to something that can help the heroes in Barovia, has well as being intimately tied to each of the heroes. Three of the cards were designated as "wild cards", and in accidentally drawing them Rose decided to take Dawn as payment.
Over the course of the adventure, Dusk has died twice. Knowing that losing the "Innocent" fate would bring about terrible consequences, she instead traded for two other fates. Ebb has lost his "Raven" fate, and Klaus has lost their "Miser" fate.
In order to increase their chances of success, Madam Eva redrew the heroes' fates, adding an extra card to replace the missing high card.
This card tells of history. Knowledge of the ancient will help you better understand your enemy. Go to the mountains. Climb the white tower guarded by golden knights. (Kaarle / Soldier) This card tells of a powerful force for good and protection, a holy symbol of great hope. I see a fallen house guarded by a great stone dragon. Look to the highest peak. (Meti / Abjurer) This is a card of power and strength. It tells of a weapon of vengeance: a sword of sunlight. A wounded elf has what you seek. He will part with the treasure to see his dark dreams fulfilled. (Spark / Beggar) This card sheds light on one who will help you greatly in the battle against darkness. A Vistana wanders this land alone, searching for her mentor. She does not stay in one place for long. Seek her out at Saint Markovia’s abbey, near the mists. (Unfated / Mists) Your enemy is a creature of darkness, whose powers are beyond mortality. This card will lead you to him! He dwells with the one whose blood sealed his doom, a brother of light snuffed out too soon. (Dusk / Innocent)
This leaves Nine-Fingers' "Warrior" fate, and Tanner's "Myrmidon" fate as wild cards.
The heroes have figured out that their fated ally is Ezmeralda D'Avenir.
The heroes suspect that Argynvostholt holds one of their fates.
