In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her seemingly charming suitor, Castello, in their whirlwind romance. His tasks include ridding the canals of monsters, procuring alcohol, and selecting a wedding gift for Triss. The gift's significance is noteworthy; a memory rose, a callback to The Witcher 2, elicits a strong emotional response from Triss, unlike more mundane choices.
However, the impending nuptials take an unexpected turn. Dijkstra's revelation of Castello's connection to witch hunters throws the situation into disarray. The truth emerges: Castello is being blackmailed, his secret daughter from a previous marriage the leverage used by the hunters.
Geralt faces the choice of revealing this information to Triss, either privately or with Castello present. Regardless of his approach, the wedding is called off. Triss's reaction varies; disappointment in her fiancé or gratitude for his honesty, but ultimately, the hasty marriage is deemed inappropriate.
This plot development offered a chance to deepen Geralt and Triss's relationship while simultaneously enriching the narrative of supporting characters. The unexpected turn of events adds layers of complexity to the storyline.
