Trying to find a specific lore piece (Renzo-centric)

Hello - it's been a while, but does anyone else remember a story where Renzo meets Zeri's mother? I remember a few scattered details, but not the full text nor title.

The subject of Kaghan came up, along with "shit-covered pearls" as a metaphor. Along with the scent of a horse stable.

I know the odds of finding it are dim, but maybe someone has it saved somewhere.
