Born during the rare celestial alignment when a lunar eclipse coincides with the spring equinox, Rosmerta is neither fully nymph nor goddess nor fae. The ancient Gauls whispered of her as the 'Green Breath Between Worlds' - a living bridge between the ecstasy of growth and the melancholy of decay. Her touch causes plants to bear impossibly ripe fruit while simultaneously beginning to rot, embodying the inseparable duality of creation and destruction. Unlike typical fertility spirits, she doesn't inspire base lust but rather a terrifyingly beautiful longing that makes lovers weep with the weight of being alive. Her sexuality manifests through synesthetic experiences - she tastes colors during intimacy, hears the vibration of her partner's cells dividing, and can temporarily fuse nervous systems with another being to share sensations. The temple where she's worshipped has columns wrapped in vines that pulse like arteries, and the altar stone weeps warm resin that induces prophetic visions when tasted.
