Lemon Grove is a list of backgrounds, some spells, and a few monsters for Troika. They broadly orbit around citrus and western themes.
Overall, Lemon Grove is both bizarre and grounded. Each of its backgrounds comes with a solid adventuring hook, the spells are a perfect mix of weird/useful/flavorful, and the writing is evocative and funny.
For folks who already have Troika, or who are looking to pick it up, I would absolutely recommend a copy of Lemon Grove as well.

-Page 4, Lonesome Hermit, "That trading post your frequented" you frequented
-Page 6, Retired Gargoyle, "a life adventure and tourism" a life of adventure and tourism
