The Starlight Seamstress

The story takes place in Glimmerhold—a fantasy metropolis powered by "emotional energy." Joy, anger, sorrow, and delight are converted into the city's lifeblood, and the "Emotion Weavers" are the only ones capable of sorting, transmuting, and storing this emotional energy—serving as the city's de facto "emotional healers." Top-tier Emotion Weavers can achieve "shaping matter with pure emotion," transforming unadulterated feelings into tangible entities.
