In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her fiancé, Castello, in their wedding preparations. His tasks include ridding the canals of monsters, procuring alcohol, and selecting a wedding gift for Triss. The gift's significance impacts Triss's response; a memory rose, a callback to Witcher 2, evokes a strong emotional reaction, unlike more mundane presents.
However, a shocking revelation from Dijkstra exposes Edmund's connection to witch hunters, casting doubt on his intentions. It transpires that he's being coerced—the hunters threaten to expose his illegitimate daughter from a previous marriage.
Geralt can choose to reveal this truth to Triss, either alone or with Edmund. Regardless, the wedding is called off. Triss is either disillusioned by her fiancé's deception or grateful for his honesty, but ultimately deems the marriage premature.
This unexpected turn could have significantly enriched Geralt and Triss's dynamic and further developed the supporting characters.
