In the Witcher 3's "Ashen Marriage" quest, set in Novigrad, Geralt assists Triss Merigold and her fiancé, Castello, with their impending nuptials. 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, while less sentimental presents receive a cooler reception.
However, Dijkstra's revelation that Castello is secretly connected to witch hunters throws a wrench into the proceedings. Castello's involvement stems from blackmail—the hunters threaten to expose his illegitimate daughter from a previous marriage.
Geralt faces the choice of revealing this truth to Triss, either privately or alongside Castello. Regardless of his approach, the wedding is called off. Triss is either disheartened by her fiancé's deception or grateful for his honesty, ultimately concluding that the marriage was premature.
This plot development presented an opportunity to enrich Geralt and Triss's dynamic, while also furthering the narrative arcs of supporting characters.
