She's based on a character called "Xyla", one of the romance-options and royal architect from a Stardew Valley-like game called "Sun Haven". It's surprisingly good, actually.

But since she's such a minor character that no model would know her and with no LoRAs, I had to "build" her with tags. So there are differences to the original, but it works for me.
