A wonderful little piece, Cody Steward and Jarrod Taylor (author of episode 9 of Convergence Manifesto) published Sora Esma’s Cart of Wonders on DMs Guild:
“The hobgoblin peddler Esma offers 500 esoteric trinkets to players in the world of Eberron! Players can find items from all major Eberron regions. This supplement offers players alternative options for character creation trinkets catered to the setting, as well as a chance to acquire these items by encountering the merchant anywhere in the Eberron world.“
